New AlertDialogFragment.java introduced

This is the new class for Dialog Alerts based on DialogFragment. 

It has a huge parameters list including:

* the style and theme, 
* title and message texts
* methods to be called on selection
* as well as a param for it.

Just as an example - it's connected to the onMapLongClick(LatLng coord) ...

Dialog view itself is very simple, needs some @Azrin work on it :)

If you like it, I will finish code by adding all other stuff to close  GuidedMode issue.
