[nem-en] assembly versioning

[NoiseEHC]

Can we change to versioning assemblies explicitly?
I mean change 0.9.2.* to 0.9.2.XXX where we should increment XXX by hand 
every time we really need.
The problem is that when MSBuild-ing Nemerle, the .NET loader terminates 
because the msbuild task
and the nemerle compiler tries to load two Nemerle.dll files with 
different minor numbers (0.9.2.23 vs 0.9.2.25).
