Some corrections. The most important is that NewtonSoft.Json 4.5.0.0 is refe
renced (using its public key) and, when used in a projet calling nuget, it crash
es at runtime because it can't find this version of the library
    Other corrections :
    - Hammok has to be compiled by it's own. Some project references exists but
without Hammok in the project list.
    - better handling of nuget packges under git
    - some tweaks because it didn't compile correctly on my VS2012
