We currently use a specially made username/pass to access the RH bugzilla. We need to make a generic UI that will allow the user to enter or change these value for any bugzilla instance and also a way to persist them between eclipse runs.
Working on this right now.
There apparently already is an Action class for this, I'll reuse it to prompt for the password for bugzillas that need it (i.e. Red Hat's). I'll also need to move the core functionality of storing the password and username in the Platform database into BugzillaConfiguration.
This is now added to the AddBugzilla wizard, if the information is not supplied there the LoginAction is used to prompt the user for the user name and password.
