[Patch] Search index updater script doesn't work

[Thomas Moschny]

At least in our setup, where SupyBot logs the channel contents to a new file each day, the update-irc-search script doesn't work properly. It throws a lot of IO errors, and creates subdirectories for each logfile within the irclogs.idx dir:

$ find /tmp/irclogs.idx
/tmp/irclogs.idx/#channel.20080805.log.idx
/tmp/irclogs.idx/#channel.20080805.log.idx/builtin.db
/tmp/irclogs.idx/#channel.20080805.log.idx/builtin.db/config
/tmp/irclogs.idx/#channel.20080805.log.idx/builtin.db/wordid
/tmp/irclogs.idx/#channel.20080805.log.idx/builtin.db/idword
/tmp/irclogs.idx/#channel.20080805.log.idx/builtin.db/attributes
/tmp/irclogs.idx/#channel.20080805.log.idx/builtin.db/uris
/tmp/irclogs.idx/#channel.20080805.log.idx/builtin.db/words
/tmp/irclogs.idx/#channel.20080804.log.idx
/tmp/irclogs.idx/#channel.20080804.log.idx/builtin.db
/tmp/irclogs.idx/#channel.20080804.log.idx/builtin.db/config
/tmp/irclogs.idx/#channel.20080804.log.idx/builtin.db/wordid
/tmp/irclogs.idx/#channel.20080804.log.idx/builtin.db/idword
/tmp/irclogs.idx/#channel.20080804.log.idx/builtin.db/attributes
/tmp/irclogs.idx/#channel.20080804.log.idx/builtin.db/uris
/tmp/irclogs.idx/#channel.20080804.log.idx/builtin.db/words
[...]

The attached patch replaces irclogs/console.py with a version that fixes the issue for us. The idea is of course stolen from the parse_refactor branch.
