Use AssemblyName

Close #602

It works well for me. Assembly > csproj > class name.

The issue that #602 raises is the need for build systems to know what the name of a tool's output will without having to know the contents of the inputs.

I'm fine with nccs to using the contract name as the base name of the generated .nef/.manifest.json/.nefdbgnfo files by default. #602 is proposing the addition of a mechanism so the build system can override that default.

Adding an --assembly-name (or other similarly named) command line option enables the build system to override the default base name, regardless if nccs is provided a single .cs file, a .csproj file or a directory of .cs files.

Parsing the AssemblyName property out of the .csproj file is more complex and doesn't provide a mechanism to control output base name for the single .cs file or directory of .cs files solution.
