Search icon added in the Action Bar

Search action still not implemented
OptionsMenu and SearchResults activities added

1) OptionsMenu activity holds the common actions in the action bar.
Right now it holds only the Search Action. The OptionsMenuActivity
extents FragmentActivity. If an activity needs a search action it must
only extend the OptionsMenuActivity.

2) The SearchResultsActivity handles the search query
Search submit button added

It took me 3 hours to make the search action to redirect me to the
SearchResultsActivity. There is nothing in developer.android that tells
you to put a meta-data for the whole application to set the default
search activity.
