* renaved Text::Markdown::XS to Text::Markdown::Discount * added Makefile.PL and ext/Makefile.PL tweaks to create libdiscount_markdown.so
* use PREINIT * put Safefree() to see how it works * renamed _markdown() to markdown()
* don't call strcat(), making segfault (or bus error on Mac OS X), missing a line feed at the end is better than getting fatal error
