Added very rough document about how stuff works on OWRT.
Word wrapping.
Added overview text.
Added some further caveats.
Added executable bit to scripts.
Made the odhcp6c_handler.lua also executable.
Merge branch 'master' into ms-dns
Converted the code to be reasonably ~working (stuff seems to actually do something now). Next thing to do is to play with it via avahi, but that's for next week.
