Messages, make username checking case insensitive through…

…out Murmur.

The database query for looking up users in ServerDB has always been
case insensitive.

This commit makes the "duplicate user"-check in Messages.cpp case
insensitive as well.

Furthermore, this commit updates the documentation for the authenticate()
callback in to document that authenticators should strive to
make usernames case insensitive.

Fixes #1078
