Unified the way a drop-down menu button is clicked (take 2)
doc improvement
If the dependency is already installed, don't try to overwrite them.
Fixing fragile test albeit in a poor way.

When scheduling a job, the state transition of queued items happens asynchronously from the UI thread.
So if we hit the UI immediately afterward, you might not see the item in the pending state. Queue.maintain()
might not have run that to determine that it's in the pending state (as opposed to in the waiting state.)

So adding some delay artificially to work around this problem.

Ideally we should use something like waitForCond() to repeatedly test this until we find one, so that
we don't have to always wait for 3 secs, and instead wait at most 3 secs.
got rid of this 2nd argument after some more thought.
Fixing test bug.

The relative path resolution logic now removes redundant '/', so we cannot produce this weird path expression
Minor comment updates for GerritTriggerTest.
Merge branch 'patch-1' of https://github.com/itgkarl/acceptance-test-harness
Bind DN optional for ActiveDirectortTest.
Fixed @WithPlugin again: we need to be able to overwrite existing but outdated plugins that are pre-packaged in  Jenkins war.

Added one LDAP test to the smoke test suite: this test requires an update of the pre-packaged ldap plugin to at least 1.8.
