GIB. Added some breakpoint GIB builtins for debugging script/intepreter
interactions. Made carne work properly again (local variables don't
disappear in interactive mode)
changes. There still remains some bugs to be squashed, a feature or two to
add, and some polishing to be done. However, it seems to be in a workable
state.
parser a bit to accomodate this. Backslashes in double quotes are now only
removed if they escape a character that can't be written normally, or
another backslash. Removed start position support from string::findsub
since variable slices can be used instead. Added support for regular
expressions in the form of regex::match, regex::replace, and
regex::extract. Checked in regex.c from GNU regex 0.12 for platforms that
do not have regex functions in their standard library. Two minor changes
were made to this file to fix gcc warnings. Prepared the path transform
function for a change to a filesystem rooted at fs_userpath instead of the
current gamedir, but these changes are commented out pending security
considerations.
