Fix support function match patterns

[Ingramz]

Fixes following errors found from TextMate's stderr:

ERROR unmatched close parenthesis ((?i)\bMongoDB\BSON\(to(JSON|PHP)|from(JSON|PHP))\b)
bad begin/match pattern for support.function.bson.php
ERROR unmatched close parenthesis ((?i)\bUI\(Draw\Text\Font\fontFamilies|quit|run)\b)
bad begin/match pattern for support.function.ui.php

I think the grammar is generated which is why these backslashes were not escaped.

I propose changing line 33 in generate.rb to this:

list.map! { |term| Regexp.escape(term).unpack('C*') }

And then re-generate the grammar.

@infininight Do you have a handle on this?

As @sorbits said this part of the grammar is auto-generated and I missed manually correcting these escapes after the generation. The script has been corrected in 83298a0 and rerun based on 7.1.7. Thanks for the note.
