Mono 2.2 RC1 added to Openembedded

I recently added Mono 2.2 RC1 to OpenEmbedded.  The last usable version of Mono in Openembedded was 1.2.6, so this is a big step up.  Lots of interesting things have been happening since then (like Full Static Compilation) that continue to make Mono interesting for embedded.  There is still plenty to do yet such as clean up the packaging, and update the other related recipes such as mono-xsp, and gtk-sharp.
