PATCH: highlight comment blocks

[Doug Kearns]

This enables folding of multiline comment blocks and is enabled by
default. It can be disabled by defining the ruby_no_comment_fold
variable.

I'm going to have a look at simplifying the syntax based folding. It
seems to me that it might be best to reduce it to simply folding
module/class/method definitions, comment blocks, and __END__ data
blocks.

Would anyone object to longer having the rest folded? If so, that too
could be configurable. ;-)

Any thoughts?

Thanks,
Doug
