Removal BaseItemGrindFragement & support multiple pages(search).

I found out that the IGT & BIGT were basicly the same.
There was only a slight diffrence: the activity context.

Removed the do crouton methode and the booleans on SearchActivity.
The BaseActionBar is now using a static string for the query.
Bugfix 10 crouton messages when host/api is offline or doesnt exist.
Merge pull request #106 from ratan12/Search_&_IGF
