Fixed Android build by renaming the assembly.
Merged in upstream changes.
Version bump.
Synchronized namespace and assembly names so every platform will work.
Configuration fix: any CPU build for WP.
Renamed root ns to MvvmCross.HotTuna.Plugins.

The "Mvx" namespace clashes with the Mvx class in Cirrious.CrossCore,
breaking the build of my work projects... This version is safer, like
the 1st party plugins.
