improved regexp handling

Browse Source 
If regex_compile() fails, free the regexp before doing anything else
in case failure reason is "out of memory".  Feedback to the user is
highly likely to panic or crash after memory runs out; this should
let the regex failure message be issued and the game continue.

User sound regular expressions were never freed.  This frees them
when FREE_ALL_MEMORY is enabled.
