Fix off-by-one line number in JS error reporting.

Browse Source 
Post SM60 upgrade, CompileFunction started actually adding a line in
front of the source buffer, shifting the error reporting in the
simulation and other callers of LoadScript.
The GUI isn't affected as it uses LoadGlobalScript, which uses Evaluate
directly.
