* Added a script based on, but massively refactored from, DJ Delorie's DIL footprint generator (dilpad.cgi); it is dilpad.pl. It uses the command line instead of CGI, so it is suitable for repeatedly regenerating a footprint while tweaking parameters. Definitely beats doing it with a web form.
* Added a script that generates several of the existing footprints using dilpad.pl.
* Renamed some of the footprints.
* Added symbol Dual_N_and_P_MOSFET.sym, which is intended to match TSOP6_G1S2G2D2S1D1.fp.
