Add metadata for osm-contributor (but keep disabled due to crashlytics)

This was my first attempt at adding an app from the submission queue.
Contains google analytics, replaced with NoAnalytics. Also contains
crashlytics and an as-yet unpublished .jar file for license-gradle-plugin.
The older versions are on jcenter, so this will likely get published
at some point.

Opened an issue at https://github.com/mapsquare/osm-contributor/issues/1
to see if they can do a build without crashlytics.

+Summary:OpenStreetMap Contributor Mapping Tool
+Description:
+The Openstreetmap Contributor app allows anyone to contribute to OSM. It enables
+those-who-know to easily manage a group of newbies as the contribution process
+is intuitive and easy. The App comes in three flavours: store (for the Android
+Store version), poi-storage (for MapSquare POI Databases), and template (for the
+osm.mapsquare.io tool for Mapping parties). Bring your MapParties to a whole new
+level!
