Merge pull request #5 from gerryhigh/master

Add XHUD
Delete unnecessary AboutResources.txt
Renamed attributes to avoid collisions
Added project reference to actual HUD project back to the Sample solution
Added MaskType.None which will allow the HUD to display while still allowing interaction with the views below.  Also added a sample in the sample app for this
Made ProgressBar a more sane size so it doesn't get all pixelated up in the view
Finally fixes #2 by adding a cancelCallback :)
Fixed non-centered (vertically) toasts.  Also tried to clean up the Dismiss method to get context more cleanly if possible.
Updated README
Fixed layouts so that they will expand the HUD if the message is longer (and added demo's to the sample for this case).  This should deal with #3 as well!
Merge branch 'master' of https://github.com/gerryhigh/AndHUD into gerryhigh-master

* 'master' of https://github.com/gerryhigh/AndHUD:
  Format change to match other methods;
  attr name changes
  Added overload to match changes for BTProgressHUD

Conflicts:
	AndHUD/Resources/values/attrs.xml
Switched all ApplicationContext synchronization calls to be Send instead of Post.  Post is asynchronous and was causing some interesting race issues, whereas Send should be synchronous and make things work properly...
Fixed textviews to centre the text in them with the new layout wrapping changes that were previously committed.
