- Switch to the tar.bz2 distfile (it is 37% smaller)
- Fix a segmentation fault (patch obtained from Gentoo)
- Define LICENSE (GPLv2) and make GUI compulsory for now (when configured
for non-GUI, it doesn't install universally required `gftprc' file, and
generally requires more work to correctly decouple frontend programs)
- Rename one ::-containing patch file, remove unneeded ones
- Cleanup MASTER_SITES, update pkg-plist and pkg-descr
