Omnisharp now uses libPaths and sourcePaths defined in custom .rsp file

[ByronMayne]

This values were always being parsed but they were not being used. Here is an example of a .rsp file that I am using

# Core References
/using:System
/using:System.Core
/using:Microsoft.CSharp
/using:System
/using:System.IO
/using:System.Collections.Generic
/using:System.Console
/using:System.Diagnostics
/using:System.Dynamic
/using:System.Linq
/using:System.Linq.Expressions
/using:System.Text
/using:System.Threading.Tasks

/loadPaths:C:\\Users\\byron\\Desktop\\scriptingIncludes

All CLA requirements met.

this looks good thanks. I would ask for some tests but we don't have any for RSP at the moment, so it's fine 😃

Oh awesome, I thought it was going to be discussion instead of approved right away!

Right now the json schmea for omni sharp does not have a member defined for the rspFilePath field. Where would that be added?

I have a few other minor changes after using this for a bit but I will create another PR.
