Added toString method to Review for easier debugging.
Converted LavatoryDetailActivity to use a ListView for the entire
activity; needed for the list of reviews at the bottom.

Wrote the Adapter for LavatoryDetailActivity.
Almost finished the LavatoryDetailActivity for the alpha release.
Adjusted sizes of the RatingBars in the LavatoryDetailActivity. Changed
TODO comment on addReview().
Made review list elements in LavatoryDetailActivity not selectable, as
the ReviewDetail Activity is not yet implemented.
Keith: Added rudimentary ListView stuff
Added stub methods for all unimplemented actions in the action bars for
each Activity (the stub methods display a Toast). Added comments. Made
formatting consistent across all Activities (using Eclipse's Source >
Format menu option).
Merge branch 'UI' of https://github.com/swansond/LavatoryLocator.git

Made the AddReviewActivity scrollable in case the user enters a very
long review. Cleaned up string resources as well as made them
consistent.
Finished the UI for the AddLavatoryActivity.
Merge pull request #24 from swansond/UI

Minor style things aside, it all looks good.
