Don't hang when confronted with urls which require authentication

When faced with an url that requires authentication, irkerhook currently blows up rather messily, because urllib.urlopen attempts to prompt the user for a password, which unsurprisingly fails, leading to the hook failing completely with an EOFError .

This changes irkerhook.py to use urllib2 here, so this failure can be detected more easily and the a more sensible answer can be returned.

The debian package currently uses the more heavy-handed "0004-webview.patch" to solve the same problem - http://anonscm.debian.org/viewvc/python-apps/packages/irker/trunk/debian/patches/0004-webview.patch?revision=12689&view=markup

Fix confusing / incorrect instruction in install.txt

install.txt suggests to use options -d 1 or 2 to control logging output,
when in fact irkerd uses the syslog levels. Changed to say -d
info / debug, so we don't get an error when doing as the install
instructions suggest.

Use getaddrinfo to connect to IRC

This allows irkerd to connect to e.g. IPv6-enabled IRC servers.

Fix logdev checking on Debian Jessie

Irker expects only one of (`/dev/log`, `/var/run/syslog`,
`/var/run/log`) to exist, however on Debian Jessie, we’ve got
`/var/run/log` (which is a directory), too.
