[BB10] Fix: Don't set a reminder when adding to calendar.

It appears that when creating a new CalendarEvent object on BlackBerry 10
its reminder is set to "At Start" instead of "No Reminder".
[SYM, BB10] Delay starting search one second after user stops typing.

On Harmattan it looks like onTextChanged signal is fired only after a
whole word/space was typed in. But nn Symbian and BlackBerry it's fired
after each letter was typed. So, not to flood a server with search
requests, we're only starting a search one second after user stops
tpying/deleting the text.
Also start search when Return/Enter is pressed.

Don't start search when input text is empty.

A few small fixes
[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.
