01 Regex flags explanation in search tooltip

This is probably used quite scarcely, but I find the tool tip in Eclipse very useful to remind me of what the various ismd flags really mean.

Support for the COMMENTS (?x:...) flag has been around for ages:

- http://docs.oracle.com/javase/1.5.0/docs/api/java/util/regex/Pattern.html#COMMENTS

... and in Java 7, support for the UNICODE_CHARACTER_CLASS (?U:...) was added

- http://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html#UNICODE_CHARACTER_CLASS

It would be great if these flags were also documented / supported from the Eclipse search feature. Probably, a version-check would need to be done to see if Eclipes is running on Java 7 for UNICODE_CHARACTER_CLASS
