MoonSharp clobber syntex error details during require

[fgretief]

Calling the require function on a file with an syntax error in it, MoonSharp print the point where the required is called, and not the place were the syntax error occurred.

In MoonSharp the following is given:

> require "test1"
libfunc_require:(12,1-44): unexpected symbol near '/'

I traced the issue to the FillDebugData call on line 249 in the Processor_InstructionLoop.cs file. This method overwrite the Decorative message of the SyntaxErrorException that already contain the correct Decorative message. If I add an if statement to not write the decorative message for SyntaxErrorExceptions in FillDebugData method, then the result is as follows:

> require 'test1'
test1.lua:(5,1-2): unexpected symbol near '/'

This makes it easier to understand where the error comes from.

In Lua 5.3 the error message is much more consistent:

> require "test1"
error loading module 'test1' from file 'W:\workspace\lua\test1.lua':
        W:\workspace\lua\test1.lua:5: unexpected symbol near '/'
stack traceback:
        [C]: in ?
        [C]: in function 'require'
        stdin:1: in main chunk
        [C]: in ?

I'm running into the same issue and it makes it nearly impossible to write/debug multi-module Lua code. I'm using the DLL in Unity, so I don't have a full .NET environment set up. Any chance of a quick fix? Otherwise I'll try installing Visual Studio and creating a pull request.
