Add workaround for start mechanisms when not SportBukkit

 - The hasSportBukkitApi() check is moved inside the loop, so that the loop is run even without it.
 - We add a new code block inside the loop when SportBukkit is not present. The code block first determines what block to do using the Attachable interface, or just uses DOWN if it's a pressure plate.
 - Once the block to update is determined, we set it to air with NO updates, then to its previous value WITH updates, which causes the desired redstone updates. This is because we don't have a way to ask for physics if nothing has changed.
Allow pressure plates to be used as start mechanisms
Cancel referees and streamers from activating pressure plates. Fixes #169

(Optionally) send AutoReferee protocol messages to API via PUT

Resolve 9 FindBugs bugs

Resolved:
 - team.getExpectedPlayers() is a collection of String, not Player
 - setConsoleWorld(String) might pass null into setConsoleWorld(World) which then calls world.getUID(). This is replaced with setting explicit null (the startup value).
 - (x3) SportBukkitUtil must be prepared to encounter Errors as well as Exceptions and ignore them too
 - (x3) Renaming Exception parameters to 'ignored' when they are ignored
 - Comment out unused player in unit test

Unresolved:
 - The fields of MatchParams and TeamInfo are never written by code
 - CombatListener is guaranteed to reference vapl, despite there being a nullcheck there
Send match destroy message to referees/node. Closes #177
Provide some options for additional gamerules. Closes #179
