[Staging] 3.1 (#1502)

* Fix handling of wildcard help text

* Rewrite help text for better handling of params

* Replace misleading letter variable

* stash changes on branch switch, else it fails if any changes have been made.

* Make changes according to comment in #1384

* Update queryFunc()

* Remove unused processWildcards() function
* Return a message if no domain is specified
* IDN domains are converted to punycode when running a `pihole -q` search if the `python` package is available, otherwise will revert to current behaviour
* Scan Blacklist & Wildcards first, exiting from search if a match is found (Fixes #1330)
* Use one `grep` subshell to search for all "*.domains" lists at once (opposed to looping to get every matching file name, and then spawning a `grep` instance for every matching file)
* queryFunc() will not return "(0 results)" output from files where no match is found
* Sort results based off list number
* Return a message if no results are found

* Update basic-install.sh

* Update block page. Allow for setupVars setting of CUSTOMBLOCKPAGE (bool) to prevent it being overwritten

in the template section.

* Display FTL version & version.sh rewrite

While testing to make sure `pihole -v` would output `pihole-FTL version`, I noticed some options didn't work how I expected them to. For example, if I use `pihole -v -p`, I would expect to see the version output of Pi-hole Core. Instead, I'm informed that it's an invalid option.

I've had the following things in mind while rewriting this:
  * I'm operating under the assumption that FTL is only installed if the Admin Console is (Line 113 exit 0)
  * I have modified the help text to only output with `pihole -v --help`
  * I have modified all output to be more similar to the output style of `grep` and `curl` (Ditching ":::")

Testing output:
```
w3k@MCT:~$ pihole -v
  Pi-hole version is v3.0.1-14-ga928cd3 (Latest: v3.0.1)
  Admin Console version is v3.0-9-g3760482 (Latest: v3.0.1)
  FTL version is v2.6.2 (Latest: v2.6.2)
w3k@MCT:~$ pihole -v -c
  Current Pi-hole version is v3.0.1-14-ga928cd3
  Current Admin Console version is v3.0-9-g3760482
  Current FTL version is v2.6.2
w3k@MCT:~$ pihole -v -l
  Latest Pi-hole version is v3.0.1
  Latest Admin Console version is v3.0.1
  Latest FTL version is v2.6.2
w3k@MCT:~$ pihole -v -p --hash
  Current Pi-hole hash is a928cd3
w3k@MCT:~$ pihole -v -a --hash
  Current Admin Console hash is 3760482
w3k@MCT:~$ pihole -v --help
Usage: pihole -v [REPO | OPTION] [OPTION]
Show Pi-hole, Web Admin & FTL versions
  <Shows all Repositories and Options>
w3k@MCT:~$ pihole -v -foo
  Invalid Option!
```

* Update -h to work as --hash

Also provide error output as per https://github.com/pi-hole/pi-hole/pull/1447#issuecomment-300600093

* Perform EXACT searches on HOSTS lists correctly

`\s` on the end may be overkill, but it is the existing scanList() behaviour.

* Fixed indentation

* Minimise string duplication & other minor changes

Instead of duplicating output strings, rewrite core/web/ftlOutput() into one neat versionOutput().

* Modified syntax to be valid for Shellcheck

* Log and echo gateway responses

* Update queryFunc() to search Whitelist

If there is a match in Whitelist/Blacklist/Wildcards, `[ ! -t 1 ]` will cause the search to end if the terminal is closed when the script is called. This has the intended effect of allowing a user to search for a W/B/W domain (as well as all the adlists it's found in) using `pihole -q` via Terminal, but the script will stop searching after a W/B/W match when called by the block page.

* Wrap in double brackets

* Provide remote hashes for version.sh

 * Provide remote hashes for comparison
 * Use double braces for all conditions (for consistency)
 * Suppress potential "cd" error output
 * Provide "not applicable" output upon any hash request for FTL

* whitelist on website blocked doesnt work (#1452)

Since Pi-hole redirects ad domains to itself, accessing the script via de.ign.com is the same as pi.hole in this case. The fix should be as simple as adding a / before admin on this line.

* Solve piholeLogFlush.sh having to be issued 2 x to clear logs (#1460)

Simplified the command -v syntax, and added a sleep 3 timer to the first execution of the log rotation. The second execution was being issued while the first was still running, thus it would fail and you would have to issue the "Flush Logs" command a second time.

* Use `echo "ABC" | pihole tricorder` to upload to Pi-hole's medical tricorder. Uses SSL if available.

* Update list.sh

I believe this has feature parity with `sed /foo/ Id` but also supports busybox, and my alpine docker ;)

* Document `sed` substitution for user readability

Comment the oneliner with explanations of what each step does.

* Update Help Output (#1467)
