Migrate xchat-gnome configuration to Polari

Usage

make install && killall -9 mission-control

If the tool complains that the telepathy configuration file already exists and you want to wipe your existing Telepathy (not just Polari!) configuration, remove ~/.local/share/telepathy/mission-control/accounts.cfg before running make install.

TODO

• Add support for HexChat (?)
• Add support for xchat
• Add support for Nickserv passwords
