SendAnswerActivityTest Progress

Had some trouble setting up an ActivityTest, this is the progress till
now.
Small adjustments in SendAnswerActivityTest

Had to make sure the activity was closed after running a test so other
tests can be run afterwards.
Merge remote-tracking branch 'upstream/master'
Incoming question list searching

It should now be possible to search in the list of incoming questions.
Search mechanic working (No filter yet)

The search field works but there is no working filter so no results are
given yet.
Search filter functional

The list of questions is currently filtered by the text of the question,
later username could be added to the filter or it could be changed to
the title of a question when we stop using the dummydata.
Added comments

Little cleanup and added comments.
Merge remote-tracking branch 'upstream/master'
