gaimlog backend

[Edd Dumbill <edd usefulinc com>]

The gaimlog backend didn't work if GAIM doesn't log in HTML -- I have
"Strip HTML from logs" enabled in the prefs.

I attach a patch which hopefully fixes that, and it also starts to make
a stab at putting the correct conversation ends info in, but it looks
like the indexing needs rewriting to get this done properly and I've not
got the time just yet.
