Fix for #121: Unify build action conversion logic used by BuildActionConverter and BuildActionTypeConverter

Details, from Kevin:
The issue was caused by interactions between BuildActionTypeConverter and BuildActionConverter.

BuildActionConverter is used to map strings to BuildAction for use in the FSharp project system.
BuildActionTypeConverter is used to map strings to VSLangProj.prjBuildAction for use by the VS infrastructure. BuildActionType converter knows nothing about BuildActions registered by the F# project system.

The fix is to have the BuildActionTypeConverter delegate to BuildActionConverter to translate  VSLangProj.prjBuildAction to BuildActionsRegistered by the F# project system.

Longer term, we should consider a cleanup activity to make the FSharpProjectSystem use VSLangProj.prjBuildAction rather than BuildAction (changeset 1316292)

Codeplex issue: 6 - Consider using GCLatencyMode.Batch in fsc
https://visualfsharp.codeplex.com/workitem/6

I revisited this suggestion today:   I tested it out and it gave me an approximately 7% increase in compilation speed.  I will save the shelf set until we have shipped 3.1.2
