Refactor how Desktop install and locate configuration files.
Fix the Neo4j Desktop vmoptions include path, and add an option to the uninstaller, to also remove configuration and log files.
Revert the change that removed the Neo4j Desktop Install4j license injection point.

Also add a user-local plugins directory to the classpath.
Add a plugins directory feature.

 - Add a plugins directory to the installation directory where users (or administrators) can add jar files with plugins and extensions.
 - Added a button to the settings panel that opens Explorer (or the platform directory browser) in the plugins directory.
 - Obviously also added it to the launcher classpath. This was the hard part, because we wanted to put the directory under $APPDATA, but this could not be made to work with the current version of Install4j.
Fix the window-close-database-shutdown behaviour that I broke in my eager refactoring.
Revert "Temporary fix for race condition in switch to master using slave tx id generator."

This reverts commit 357fd50d2cb090d5594749330b4ecf466cfea3f9.
Get the name of the sub-directory under APPDATA from the installer, instead of hard-coding it.
Only return same relationship once.

If providing the same RelationshipType more than once to the
getRelationships() method of Node, one would get relationships of that
type more than once. This change deduplicates the types, ensuring that
each relationship is returned no more than once.

This fixes #1477.

Fixes issue where more HA availability messages than necessary were broadcast

Previous attempt in this area left open a bug where for example the master receiving
 a SlaveIsAvailable event would make it broadcast a MasterIsAvailable event again,
 refuelling a loop of such exchanges. This makes sure that the instance's state and
 the incoming transition are examined to decide on what to broadcast.
Introduces tests for the above.
