[CMake] Visual Studio 2010 Generator Missing?

[Micha Renner]

> Just a small piece of feedback. All the other Visual Studio generators are "in order", ie, VS 6, VS 7, VS 8, VS 9 so it made sense to look for VS 10 below VS 9. Was there a specific reason for putting VS 10 above VS 6 and thus "out of order"?  
The only reason I can think is that VS 10 starts with "1".

For example:  
1
11
111
2
3
4
