Added a simple GUI testing project
Add Conditional check for GTK3
Add the DebugGTK3 type of configuration to sln

Not added it to csproj, since MD seems to be wiping my changes
Made Conditional references in csproj file

Some requirements: Need to set MonoDevelop to build with xBuild (or use makefile to build)
In Monodevelop, due to a bug, all references will appear twice.
