Pre-alpha release of static page generator

It's still very much a pre-alpha, but v0.1.0 of pbwdm-static.pl is now available for developers' consumption. From src/ run `./configure.pl && make pbmodwdm` then you should be able to run `./pbwdm-static.pl $file` where $file is a Perl file constructing a PBWDM::Site object $Root.
