Reconsider regexEscaper()

[GoogleCodeExporter]

This has been asked a few times internally, and we have some internal copies of 
an implementation, mainly because Pattern.quote is available but not under GWT 
(where \Q...\E doesn't work at all).

It might be nice if GWT (and other non-java.util.regex utilities, like Google's 
RE2) provided its own literal-escaping methods.

This is particularly true because escaping can differ across regex 
implementations -- e.g., whether () are metacharacters or normal characters by 
default vs. when "escaped."

I do think that we could come pretty close to a universal escaper by preferring 
[(] style escaping over \( style, but I haven't investigated in detail.

I still suspect that this isn't enough of a priority to get done, but we'll see.
