[Mono-osx] My Github fork for samples

[Pavel Sich]

For anyone interested, I have made a version on Github, where I will 
publish the samples I convert from ObjC to Monomac.

ATM there is a first one in progress - ButtonMadness, but will add more.

Also as there are some APIs missing in AppKit, I will be adding those to 
my branch, and when eventually merging samples to the main master 
branch, will merge those as well with the current state of Monomac.

Suggestions for samples to be converted and any ideas, are welcomed.
