Update to ScriptCs 0.10.2

Remove Roslyn NuGet packages.
Update all other NuGet packages apart from Common.Logging.
Common.Logging 2.2.0 does not seem to work with ScriptCs. 2.1.2 works.
In Common.Logging 2.2.0 they split the NuGet package into two parts
and the Common.Logging.Factory.AbstractLogger type which ScriptCs
fails to resolve in 2.2.0 is moved into the Common.Logging.Core NuGet
package.
