Add another version that supports the 2560 based boards

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Take advantage of improved control code of other flight control software 
that takes more memory that the smaller processors.
2.
3.

What is the expected output? What do you see instead?
Improved control capability.  


What version of the product are you using? On what operating system?
I am using MultiWii 2.2 on Windows 7.

Please provide any additional information below.
I would probably go to the MegapirateNG but I really like the ability to 
communicate with the fc board with bluetooth.  The ability to make changes 
without having to physically connect to the board is really great.
I also believe that there will be a lot more of the 2560 based boards which 
have even more sensors available and the easy connection of gps.
