[arch-dev-public] Mono upgrade to 2.0

Hi all, I'm planning the upgrade of Mono to version 2.0. I will rebuild all necessary packages and update them, too. (For example: boo) So, if anyone maintain a package which is affected, just like the mentioned "boo", you don't have to do anything. I will build and package those in one run for both architectures if it's necessary. Daniel
