Updated the Bathroom and Review classes to fit our decided naming
policy. Removed Coordinates.java and ServerInterfacer.java because they
were more harmful than helpful and so we don't use them anymore.

Added the server querying methods to the activities and implemented
their loaders and tasks partially. They send the request to the server
but do not process the data they get back yet. The methods are also
never called yet.
Updated activities to match UI branch. Moved RequestAddLavatory() to
AddLavatoryActivity.java.
Merged with most recent UI state to get missing /res/ files,
LavatoryDetailActivity, and various other small things.

Added toString() to LavatoryData.
Moved everything from ListViewActivity to MainActivity.
Removed menu XML file for ListViewActivity, as that doesn't exist
anymore.
Added "Got2Go" icon to action bar.
Got most of the loaders and tasks working. Only the loader for getting
lavatories and the task for requesting the addition of a lavatory don't
work yet. That could just be the php's fault so I'm committing anyway.
Adjusted layout margins.
Fixed layout margins for the review item row.
Merged with UI branch, resolved conflicts, added comments.
Final merge with UI and commit before pull request.
Merge branch 'UI' of https://github.com/swansond/LavatoryLocator into UI
Added temp login system
added JSON parsing to the Loaders
fixed the merge conflict
finished parceling things
