Fix AE identifiers: reserved word $

[blake-regalia]

Fixes #72.

@bathos Not sure if this is the best way to solve this but it seems to do the trick.

Since $ is probably the only likely case to trip this, this solution may be sufficient. However I think the underlying issue is that the negative lookahead should be for the identifierPart var, because this should also be scoped as an identifier:

What’s used elsewhere, and what I think was intended to be used in these cases too, is {{idEnd}}. I think that would fix both:

Ecmascript-Sublime/ecmascript.sublime-syntax

Line 127 in 3646cb4

idEnd: '(?=[^\$_‍‍{{ID_Continue}}]|$)'

...though I wonder if that’s really supposed to be '(?=[^\\$_‍‍{{ID_Continue}}]|$)'

This should now be fixed in depth by 90a9649. Sublime/Oniguruma are now more up to date and support the ID_Start/IDS and ID_Continue/IDC properties directly. There were several old mistakes related to handling id ends where end/part/continue were mixed up which was the main issue and it’s all a bit simpler now.
