> Changes to fix CHOP-662. CHOP-662 was caused by the recent addition of lldiriterator.cpp which is used to iterate over directories. It takes a mask in the form of a glob string to use as a pattern for which files to iterate over.
> 
> Unfortunately, as originally implemented, it converted the glob to a regex pattern without escaping any legal glob characters which are illegal regex characters. As a result if the passed in mask was an illegal regex it would fail and llerrs would cause a crash.

> In CHOP-662 this happens whenever a group name has, e.g. a '+' character at the beginning. When logging in the viewer would attempt to load the group chat log file which would result in a glob starting with a '+' character and in turn to an illegal regex in lldiriterator.

> Also, the chat code was doing nothing to ensure that illegal glob characters were not being passed to the lldiriterator constructor.
