Updated for SpoutAPI changes
Make SpoutAPI not horribly slow
Fixed valid block check to not include items
Fixed NMS block set to copy tile entity data even if the original block did not change its id or data
Fixed reported bug that block #0 (air) is not considered valid.

Fixed a reported bug that block #0 (air) is not considered valid. Also set skipNmsValidBlockCheck to true if the check fails (as I assume was originally intended).
Added support for travis-ci
Removed accidentally committed file.

It doesn't contain email passwords, nuclear launch codes, or the secret to life, the universe, and everything, I swear!
Removed BukkitWorld caching.
Added some more aliases for 1.3 blocks
Only get the world's tile entity if the block id has a tile entity
Updated changelog for 5.4.3
[maven-release-plugin] prepare release 5.4.3
[maven-release-plugin] prepare for next development iteration
Modernized pom, readmes.
Removed lib/. That hasn't been needed since 1845.
No email notifications from Travis, please.
Added support for 4096 ID blocks (theoretically) in snapshots.

Also cleaned up the mess that was AnvilChunk's code.
Tabs -> spaces in README.html.
Removed NOTICE.txt. Some license used to require it but I don't think we use that library anymore.
Fixed issue with block IDs being returned negative in snapshots.
Fixed //limit being overridden each time a LocalSession is fetched.
