Special login:
Added feature that logs into accurev using the -n flag to create a never ending login session.

This is to prevent a situation where an agent is logged out in the middle of a build causing the build to fail.
Be advised that this feature cannot be disabled from the vcs config page.

hideChanges:
changed the name of ignore changes button to hide changes to better capture its purpose.

promote failure message:
fixed a bug so that the plugin will only display a message saying that an automated promote could not be done if an automated promote was requested.

better error Messages on VCS config page:
Added a more conprehensive check of the details entered on the VCS config page.
Before certains values where not checked for validity, but now as many as possible are checked.
