[gopher] more Overbite stuff

[Cameron Kaiser]

I'm monopolizing the list lately, but some stuff for public comment.

1) Now that SeaMonkey 2.1a1 supports using install.rdf rather than install.js,
this makes converting OverbiteFF to OverbiteSM (?! -- better names solicited)
much more straightforward. This is especially important as SeaMonkey 2.1,
being based on Gecko 2.0, also lacks Gopher. Is there interest in this?

2) I'm considering adding a navigational aid to Overbite such that people
can browse partial paths more intelligently. The reflex with something like

	gopher://foo/0/directory/file

is to take file off, yielding

	gopher://foo/0/directory/

which doesn't work, of course -- it gets rendered as a text file. So I'm
suggesting a simple aid. If the path ends in /, and the itype is not 1
or 7, pop a redirect to change the item type to 1 for the user automatically
(this is done within the channel; it doesn't hit the server). I could have
it pop up a dialogue box to suggest the change rather than just doing it if
people like that idea better; it could be rolled into the code for
newProxiedChannel with the other checks.

This won't cover everything, but it should cover many things. I don't
really want to go hunting for tabs, because tab characters could be in
legitimate documents (unless someone can propose a semi-reliable algorithm).

Content sniffing is not possible the way the docshell is designed because
the simulated MIME type is already computed from the itype; as soon as the
load starts, it's too late. So this has to be handled at the channel level.
