[Javascript] Text Field Arrays

[TomMallard]

Are the brackets in the name of a form element legal? Those are
operators...pretty certain they're not legal characters used as form element
names. Nice trick, but I think you need to rename them...like
'files_description_00', I've used this style for auto-numbering a lot.
