capmt: fix crash while trying to open iptv channel with capmt enabled
Add missing command line options to the man page.
Allow binding address to be specified via --bindaddr flag.
build: update build system to fix some odd use cases
ui: fix previous mod that broken channel configuration editing

I made the change so that /channels returned the imagecache icon
while I was testing some other UI code. Unfortunately that breaks
channel editing. So I've added a second (possibly confusingly named)
field.
