Do not finish WelcomeActivity when showing about info
Properly set sound notification (fixes #117)

Set the ringtone URI to the default ringtone if sound notification is
enabled. Set it to null otherwise.

This fixes the problem that sound notifications are not sent anymore
once the user has disabled and then re-enabled them. The reason was,
that the ringtone URI would never be set to a valid value once it had
been set to null.
Limit port input settings to 5 digit numbers

The user can now only enter 5 digit numbers as server ports.
Show toast when start-/stopping encrypted chat

Instead of displaying a progress dialog simply show a toast message and
perform the requested action in the background. The warning view and the
options menu entry are updated once the action has been processed.

This fixes issue #42.
Extract toast message strings to strings.xml

Since the messages are displayed to the user when enabling/disabling OTR
for a chat, we should make it possible to localize them.
Do not leak locale alert dialog
Fix language name for German (Deutsch)
Automatically cancel read certificate notification

Cancel a certificate statusbar notification once the user has read it.
Otherwise it will stay in the statusbar as long as the user does not
explicitly clear all notifications.
