Fixed crash on file editing

Implemented project filter function

This feature adds a checkable menu option to toggle wrapping lines of
code and commit messages to the width of the screen in DiffActivity.

This was achieved by creating a custom HorizontalScrollView with an
onMeasure method that measures its child with an exact MeasureSpec of
its own width. If wrapping is disabled, the super method is called,
making it act just like a normal HorizontalScrollView.

This removes code I left in to print out in LogCat if the application
failed to retrieve the commit data from the server. This does not use
Crouton to show an error message if it failed to connect, because the
diff CallBack already does this, and if it failed to connect to the
server, it would display two error messages.

This commit modifies the API slightly to allow retrieving the git commit
message from a commit, and displays it in DiffActivity. A new View is
created, MessageView, responsible for displaying the text from the
commit message, similar to DiffView. No formatting is done to the text
yet.

App crashes trying to view particular diffs (bugfix attached)

if the end of a file was changed the app could crash while trying to render "\ No newline at end of file"

feature request: default branch

Fix: endless refreshing animation

loading a project view the default branch specified for the project instead of the first available branch
