Add basic handling for `qqwrx` syntax, as well as `HASH` syntax.

Unfortunately I don't know a way of making it keep the brackets and q syntax from being part of the string syntax coloring, but this at least visually looks better than normal.

So, @Guldoman already reamed me about this last time; please bump the version in the manifest.json for this plugin.

@adamharrison Should be good to go.

[rawleyfowler]

@Guldoman Should be good now. Thanks.

[rawleyfowler]

Sounds good, thanks!
