Cancel jobs when a new patch set is created

When a new patch set is posted, building the previous patch set
is no longer valuable. This causes an enormous extra load on the
build servers. If someone rapidly posts several revisions of a
patch, it could cause enormous delays and wasted resources in
Jenkins.

This only does part of the work, because calling cancel() on a
Future that is provided by scheduleBuild2() does not cancel jobs
that are in the queue. A ticket has been created to address this,
available at: https://issues.jenkins-ci.org/browse/JENKINS-12152
Merge pull request #8 from VestniK/custom-url

Custom url
Added triggering on filepaths.

Makes it possible to add one or more filepaths per Gerrit project
in the UI. The job will be triggered only if the files in the
patch set match a filepath.

Added help documentation and a spelling correction.

Help text for file triggering and changed the repeatable

Added the possibility to check gerrit version.

It is now possible to ask the trigger which version
of gerrit we are connected to. This can be compared
to a feature version to enable/disable functionality.

Synchronization and NPE fix of runningJobs.

Null checks and synchronization of the map of running jobs.
There where problems when the trigger was deserialized,
that could cause NPE to be thrown.
Also added synchronization to avoid dirty writes.

I still get unexpected behaviour with this feature;
builds fail to cancel and it somethimes ends up
in a strage state, so I put it as more optional
than before and changed the default to be off.

WiP: Add support for triggering jobs on the change-merged event

Added a new event ChangeMerged to encapsulate the change-merged Gerrit
event, and added a new class GerritTriggeredEvent from which all event
classes are now derived.

Existing code is refactored to use GerritTriggeredEvent instead of
PatchsetCreated.

Since not all Gerrit events can be scored, extended the GerritEvent
interface to include a new method isScorable.
Add triggering on comment-added.

Add new CommentAdded event class.
Add config option to trigger on comment-added event with a specific vote
category and value, ie, trigger on CRVW 2 (approved code review).
Fix problem with config screen not correctly displaying selected trigger.
Change TriggerContextConverter to use GerritTriggerEvent superclass
rather than PatchsetCreated event.
