Remove tridactyl startup messages, add input focus

All new things since I last looked at tridactyl settings. `focusinput`
now exists, and both `guiset` and `fixamo` have quiet versions now. Only
thing missing is an option to prevent pages from automatically acquiring
input focus, so that we enter all pages in "normal" mode.
