BZ 1012449 - prevent confusing stack traces showing up in logs/console.
 Zip Path shortening - coregui, part 5
  - removing gwt client class cleanup as causing compilation failures with new workspaces on linux.
[BZ 1016049] - Avoid requiring MANAGE_SETTINGS for live avail checks.

We were using a method that requires MANAGE_SETTINGS permission, which
is not what we want here. If a user has perms to view a resource (which
is checked for), they should be able to access its availability.
Stop animal sniffer from processing the client-side gwt classes, they
are now thinned from the war (for path shortening and distro size reasons)
and can't be resolved during the check.
Add back the war thinning now that animal sniffer ignores the client
classes.
Handling the NPE caused by attempting to shutdown the uninitialized scheduler from the shutdown hook during the server install.
Bug 1015589 - asking to deploy a bundle as rhqadmin results in weird "you can't assign to groups" error
Remove the unnecessary code-path allowing the bundle to be selected in
the wizard.  It was using the wrong selector widget and we don't currently
have a widget that would make it work.  It's actually easier and safer to select the bundle from the bundles list view, or the bundle details view,
where the permission check is already performed.

This gets rid of a class, which is always good given our huge GUI.  And it
reduces unnecessary flexibility, which ends up just being confusing.
