This commit includes the major changes between DAVdroid and EteSync. It
adjusts the app to use the EteSync protocol and server. It includes some
ugliness still, and it's a squash of many ugly snapshot commits while
hacking on the initial DAVdroid code.
History should be "clean" from this point onwards.
* HttpClient: authentication that is limited to a host name is never preemptive
* DavResourceFinder: service configuration == null means that this service is not available
* new SQLite database for CalDAV/CardDAV services
* added AccountDetailsFragment, which asks for account name and then finishes account creation
* updated AccountListFragment
* remove VJOURNAL/notes sync (will be implemented later)
* setup: add "install Tasks app" fragment
* version bump to 0.8.0-beta1
* use Tasks instead of Mirakel
* handle task list colors
* allow independent selection of calendar/task sync for the same CalDAV calendar
* minor refactoring (don't use return value of Builder)
* handle more task fields and time zones
* sync interval setting for tasks
* always notify user on SSL/TLS exceptions (closes#447)
* re-organize UI classes to separate ui package
* re-organize layout and menu resources
* make MANAGE_NETWORK_USAGE intent filter work
* new Settings activity
* Settings: display/change user name, password, preemptive auth.
* Settings: display/change sync. interval for contacts and calendars
* requires permission GET_ACCOUNTS to list accounts in Settings
* requires permission READ_SYNC_SETTINGS to display current sync intervals
* remove obsolete files from res/
* update copyright notices
* version bump to 0.7
* remove debug settings activity; logging can now be enabled via adb setprop, since that's the default way of enabling verbose logs in HttpClient's Android flavour and adb is required for viewing the logs anway
* update i18n accordingly
* moved all dependencies to gradle instead of shipping .jar files in the app/lib directory
* switched to official Android port of HttpClient instead of httpclientandroidlib
* new .gitignore and project files
