glx2 script editor updated

[Malte Brill]

Hey Mark,

just took the time to dig a bit...looking at the doCompile handler:

        errorDialog theResult, the cScriptErrors of stack "revGLX2 code"


the cScriptErrors of stack "revGLX2 code"  is empty. 


Thus throwing the error dialogue fails here. 

All the best,

Malte
