* CardDAV PUT: send VCard 4.0 contacts if the server supports it
* import Apache httpclient-android rev. 1652769 correctly (hopefully fixes#491)
We can't use a repository version because there's no release yet which
contains rev. 1652769. However, this revision is necessary to get SNI with Android <4.2, too.
To avoid packaging a pre-compiled jar, this source lib has been added as a subproject:
apache-httpclient, branch 4.3.5-android, revision 1652769
Fixes#491.
* Event class finds and processes exceptions of recurring events
* workaround for iCloud and other services that provide RECURRENCE-ID as DATETIME even if the original event is an all-day event
* VEvents are generated with all time zone definitions (including time zone definitions of exceptions)
* added SQL filter possibility to generic LocalCollection
* added exceptions of recurring events to Event
* process exceptions of recurring events in LocalCalendar
* 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
* if well-known URI detection fails with I/O errors, ignore it instead of aborting
* if current-user-principal is not supported by the server, use the user-given URL is the principal URL
* determine availability of CalDAV/CardDAV by whether a calendar/address-book home set is available
* if DAV:displayname is not available for a collection, use its URL path instead
* remove SSLPeerUnverifiedException handling (Apache HttpClient doesn't use this exception)
* use Depth: 1 (instead of Depth: 0) for multi-get REPORT requests
* don't display address books in "Select collections" UI if CardDAV is not available
* don't display calendars in "Select collections" UI if CalDAV is not available
* version bump to 0.6.12
* SSLConnectionSocketFactory is now SNI-capable, so there's no need
to manage SNI in DAVdroid
* keep secure protocol/cipher suite definitions
* use a patched jar until https://issues.apache.org/jira/browse/HTTPCLIENT-1591 is fixed
* make it work again with non-proxied connections
* add tests for proxied and non-proxied connections
* add tests for SNI, host name and certificate verification
* SNI now works for proxied connections, too
* "Cannot verify hostname" message removed and split into two localized messages: one for unknown certificates, the other for hostname mismatch
* 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
