Merged my libraries into adapter-kit

Hi Ragunath,

I have added my GridListAdapters (147 Stars) & EasyListViewAdapters (50 Stars) libraries into your adapter-kit project, 
Changes:
1) I have changed package heirarchy of your library to include my adapters as well, also segregated your adapters into separate packages. (Refer "upgrading from 1.0 to 2.0" in README).
2) Also I have added my sample fragments into your Sample app.
3) Made README more detailed & attactractive.

Please accept my pull request.

Thanks
