If the hosted bug tracker is not readable by
an anonymous connection it is necessary to
provide valid credentials to fetch jira information.

These adds support to add username and password
for a simple authentication.

Added this patch, saved settings with empty username
and empty password. Saw that it cannot fetch any
information from jira as the connection is not
authorized.

Saved the settings wird a valid username and
valid password. Saw that it can fetch all
information.
