Updated to 1.2, added new permissions and config

Added perms to the plugin.yml and changed to version 1.2

Added two new permissions to allow server owners to only save XP or only
save inventories, or both. Also two new config options.
Squashed a bug

Squashed a bug where players could have the pvprestore.keep permission
node, but if a server owner set a config setting to false it would
ignore this node.
