ShrinkUrl: use x0 by default. Fixes #617.

x0 has the smallest working output. ur1 had the second smallest.
Their difference is one character.
debian/control: Replaces supybot

It was just said at #Limnoria that someone couldn't install Debian packages
 of Limnoria, because haven't been configured to replace supybot.

NOTE: I am not Debian packager, so I have no idea if this works, so please
test it first!

RSS: Change 'New news' to 'News' in announcements

'New news' sounds redundant, and the plugin is known for reannouncing
olf headlines anyway. ;)
RSS: Update translation files
Relay: make default config better.

Enable colours: most of people want them and they are supported by
all IRC clients used nowadays.

Show hostmask: that is standard behaviour of relaybots which I am seeing.

Punish other relaybots: Does this even need explaining? "Let 2009-11-24 <http://echelog.com/logs/browse/supybot/1259017200> be a lesson to you: turn *on* supybot.plugins.Relay.punishOtherRelayBots."

Don't join on all networks: I think that people mostly want to relay
specific networks, not all of them. This is also a method to evade
limitation of LinkRelay ( ProgVal/Supybot-plugins#11 ).

Use notices with nonprivmsgs: This is also standard behaviour and makes
it easier to see the difference between PRIVMSGs and everything else.
Relay: fix gender neutral pronoun & update messages.pot
README.txt: add note about joining manually on relayed networks.
Relay: fix typo (parts --> part).
Relay: update *.po
Relay: fix l10n-fi.
.travis.yml: run sandbox/check_trans.py
