importing kopete logs

[David Edmundson]

Nicely done. I'm up for going down this route.

TODO List:

As this is a bodge, we should probably talk to Tp upstream.
Check it all loads in the log viewer (I'm thinking it might not (if
your account names don't match))
We need prevention for "double imports". (i.e running your script twice)
We need a UI. I'm thinking maybe a first run wizard on the log viewer.
