Fixes an issue when using a version of python-bugzilla below 2.0.

• Fixed a bug when requesting a new module repo
• Improve the logic that determines the FAS user from a Bugzilla email address (this is used to determine if the user approving the Bugzilla ticket is a packager)
• Fixed a bug when a user requested a new repo with the "Fedora EPEL" product selected on their Bugzilla ticket
• Slight improvements to the documentation

Changes:

• Set the user agent string to "fedrepo-req/version"
• Add a way to skip Bugzilla ticket validation in fedrepo-req-admin
• Explain when a user can't be found in FAS
• Don't use the Bugzilla authentication cache on fedrepo-req
• Change requirements from "git" to "git-core"

Updates to v1.4.0. The client tool is mostly unchanged except that it has a few usability improvements such as having a man page and telling users to read the README if they haven't configured the client tool.

The admin tool has a few enhancements and bug fixes that are listed in git.

Bumps to version 1.3.0
