Add <&bs> - backslash tag

I had to rewrite a bitttt of the character escaping to allow this to
work, but it seems to all be fine. Also fixed a tiny mislabeled tag
meta.
More debug information in dB submit

Debug submit information will now begin with:
CraftBukkit Version, all plugins with versions, all loaded worlds and
all online players.
Fix location definition in scripts ran by 'Push'

If you PUSH an arrow into a mob, the arrow disappears before the script
is ran, so the location isn't recorded. This will record the last-known
location before collision.
Merge pull request #538 from mcmonkey4eva/master

Pull requests, yay!
Allow only spawned NPCs to chat. (Otherwise stacktrace error)
Add a 'player edits book' event

an event for when a player edits/signs book, see added meta for infos.
Also fix a few typos
Add book script meta+add 'signed' option to books

use 'signed: false' to make the item a book_and_quill instead of a
written_book. Thus reducing need for item script / book script combos.
Debug recording efficiency

+ some code commenting.
Update to Bukkit 1.7, Citizens 2.0.11

Everything seems to work, except the fishing trait.
Catch startup error

Finally found the bugger. I'm fairly sure this one can be blamed on
Bukkit... just catch it so it doesn't break on startup.
Catch Bukkit-induced error in 1.7 - placeblock

Event is fired incorrectly every time... ignore it for now until Bukkit
fixes that.
Don't count argument prefixed with p: or path: as script argument.
Add Cuboid Enter/Cuboid Exit SmartEvent for Players.
Add outset mechanism for dCuboid to allow basic resizing of a notable cuboid.
Sneak in set_display mechanism for dItem to allow change of display name with adjust.
Merge pull request #541 from mcmonkey4eva/master

I could write a book about this pull request - MC 1.7 update as well!
Update meta (add spawn action)

Not sure how that one was missed.
Fix <npc.inventory>

NPC inventories would identify as player inv's... not good! This
properly disables it as in@npc[n@###]
Merge pull request #545 from mcmonkey4eva/master

Where would we be without pull requests
New config file to allow scripts location to be changed.
