[BB10] Removed GPS opt out option on BlackBerry.

Added a check whether GPS Location permission is set and location services
are enabled. If not, no GPS icon will pe shown in the UI.

The check is performed only at startup, so if permission was set while
application was running, the application should be restarted.
[BB10] Removed printableMethod() function - wasn't used anywhere.
[BB10] Added a startup spash screen.
