Linking shared assembly info
Removing unused assembly references

I never understood why MS includes these by default anyway.
Remove SharpZipLib

This came in as a nuget dependency, but we don't need it to build the
analyzer.
Target .net 4.0, not 4.5

Until Raven uses 4.5 everywhere, we'll stick with 4.0 unless absolutely
necessary.
Align namespaces

Raven keeps most analyzers in Raven.Database.Indexing.  Aligning the
namespaces will make it easier to consume.
