fix a lot of gnome ports that were broken on my machine

- gcab: touch again now that Homebrew has it
- gtk-quartz-engine: use path-style dependency for glib2
- epeg: tweaks
- gimp2: update to closer reflect the version in trunk, use `-append`
for more things
- libwmf: gd2 has switched its `+no_x11` variant to a `+x11` variant;
update active variants check accordingly
- weechat: add post-patch reinplace from trunk
- dpkg: wrap commentary more tightly
- try to start a portfile for msitools
- copy over libgdiplus, evolution-data-server, gstreamer010-gst-ffmpeg,
gtksourceviewmm2, libgnomedb, libgnomeuimm, libgtkhtml, enblend, gegl,
ffmpeg, libgweather, fox, and gtk-sharp to my local portfile repo to
fix builds for my machine
