Bicho client cannot accept a bugzilla username which is an email

[thetuxracer]

Since the client uses the new_from_uri method call, it cannot handle percent encoded URIs. There is no call to unescape the username. Such a scheme is necessary because login id is an email. Refer [2]. The %40 is treated as part of the username and hence causes authentication error.

Declaring a URL with username:password@host scheme, where the username contains '@' also isnt accepted as the new_from_uri method fails on the split method. Refer [3]

Also unfortunate is the situation where the password contains a special character such as '@'.

[2] pry(main)> Bicho::Client.new('https://some%40redhat.com:password@bugzilla.redhat.com')
XMLRPC::FaultException: The username or password you entered is not valid.

[3] pry(main)> Bicho::Client.new('https://some@redhat.com:password@bugzilla.redhat.com')
URI::InvalidURIError: bad URI(is not URI?): https://some@redhat.com:password@bugzilla.redhat.com

I have a ready patch where I have fallen back on env variables to gather the username and password. I wanted to know, Duncan, if there is something obvious that I am missing? Is getting the credentials from the environment something that you see ok in your mind?

I have submitted a PR#19 for this.

@dmacvicar Please let me know if this suits you and whether it lacks something.
