Updated the README.md.
Removed the map context menu.

Instead, holding on the map will directly change the location.
Changed the way the DJIA cache's size is detected to make it more stable.

The old way would have broken as soon as I had added other items to the IsolatedStorageSettings which were not Settings but not DJIA cache either (which will be necessary for secondary live tiles).
Added  a "pin to start" button.

The tile looks a bit boring and doesn't update, which will be fixed soon.
Added images to the pinned tile.

They're not updated yet.
Added an updater service for the live tiles.

This includes a HUGE moving of files because a BackgroundAgent has to be a separate project which may not reference the App project, so now there are three projects:
* App - former Geohashing, contains the App UI.
* Base - contains Djia, Geohash, MD5, and some other stuff.
* ScheduledAgent - contains the agent.
