Better handling of click events
Start alarm on launch and trigger fix
The alarm has to be started when the activity is created if it's not
present, otherwise it won't be launched untill the user reboots or
changes the alarm settings.
Also, if trigger flag is true, the initial time to trigger the alarm
should be 0.

Move all notifications stuff to FileManager
Send/share downloaded zip
Once the rom or gapps zip is downloaded, the app will open a send/share
window when the notification gets clicked. This way the user can select
and app to open the zip.
Remove unused strings
Custom gapps dev folder

There are roms that use their own gapps packages and store them in
goo.im

As it's not possible to handle these packages the same way as the
official ones (there's a spacific url to retrieve if there's a new
official gapps version), i've added the option to check a custom folder
in goo to retrieve the last package found in it.

Note that in the selected folder there must be only gapps packages.
