Added the basic map view

Adding maps requires some changes to the configuration.  Asside from
the API key, you also need the google play services SDK.  As of this
writing the newest version available from the android software repos is
incompatible with all of the emulator images and devices because
(as far as I can tell) that version hasn't been deployed yet (??).  You
can download version 9 from here:

Merge branch 'android' into android-mapview
Moved google play services library and set default centering for the map
Moved isConnected into MainActivity so we can use it elsewhere too
Added pins, all the same color currently
Added pin type and message into marker title and snippet respectively
Pins now colored by type
Added layout for pin submission process
Populated the spinner with the selectable pin types
Refactored code to draw all the pins
Re-arranged the layouts

This is so all of the edit controls are in one layout which can have its
visibility toggled.  

Sidenote: when you rearrange layouts, clean the project because eclipse
apparently doesn't make the necessary changes to R.java automatically.
When I first tested this the app crashed with a
IllegalClassCastException because it thought I was casting a
relativelayout to a spinner.
Toggling the visibility of the layout works as expected.
New pin can be placed and dragged, editing UI appears as expected.
Submitting pins works, some scenarios still break the UI though
Marker can now be deleted correctly
New marker title and snippet now gets updated when the marker is
submitted
Updated API interface to be compatible with the new version of the API

Types for comments and pins will be remapped as follows: 
"FORUM" -> "COMMENT"
"GENERAL MESSAGE" -> "ADMIN"
"TRASH PICKUP"/"HELP NEEDED" -> "MARKER"
Merge branch 'android-pins-experiment' into android-mapview
Merge branch 'android-apiupdate' into android-mapview
