RC for testing

Changes:

• Config files can use block ID's instead of Materials - allows for custom blocks on some servers
• Team chat can be spied on by mods. Use /asadmin spy with permission: askyblock.mod.teamchatspy.
• API improvements - more methods and events
• Made purge work better with large servers
• Changed minimum protection size to 0 (was 50) to enable super-close-to-neighbor-island game variations.
• French locale updated
• Warp signs can now be wall signs.
• Portals now link up if a player makes one in the Island Nether and the Island World. i.e., players teleport between them.
• Items and entities like creatures and mine carts can go through portals.
• Enderchests can be used on any island if the player has the enderchest permission.

Bug fixes

• Name changes were not being recognized properly
• Some admins saw NPE's with Essentials Protect and creeper explosions.
• Mods with bypass lock permission could not teleport to islands
• Fixed multi-home sethome exploit where players could set an extra home at 0 as well as 1, 2, etc.
• Fixed localization error with the island invite help. It was showing the /is help text and not specific text to island invite.
