BattleArena v3.9.9.12

Permission change for the plugin.yml:

The problem is that too many people are asking about permission nodes.
The BattlePluginsDev team doesn't mind helping people with their issues,
but this is taking away from other things that we could be doing.
Like fixing bugs or adding new features.

Additionally, default permissions will make it easier for new servers (and
especially new admins) to setup & use BattleArena.

Therefore, by default, all players will have permission to join arenas
(via the join command and via join signs). Most servers will probably be
setup this way, anyways.

For those servers that want more fine-grained control over who can join
arenas, those servers can use negative permission nodes.

PEX command:

pex group default add "-arena.join.arena"
pex group default add "-arena.join.team.all"

yields a PEX permissions.yml like this:
permissions:
    - -arena.join.arena
    - -arena.join.team.all

Check the documentation for other permission plugins on how to do negative
permission nodes. But I believe bPermissions uses the caret (^) symbol to
denote negation.
