Add option for warning on placing tile entities without entity tiles. See #689, #603, #470, #243

CraftBukkit logs and a warning and stack trace when setChunkBlockTileEntity()
is called on a block in the world which doesn't support tile entities. Vanilla
simply ignores this condition, without logging anything.

This commit adds a new configuration option to bukkit.yml, mcpc
warn-place-no-tile-entity, to switch between CraftBukkit and vanilla
behavior.

By default, this option is on (matching CB), since it can help detect
legitimate bugs where a tile entity is misplaced. But since vanilla doesn't
warn, you can set warn-place-no-tile-entity: false to reduce this log spam:

Attempted to place a tile entity ... where there was no entity tile!

See #603, #243, #303, #470, #407, #397, #596, #386, #34, #457, #689,
and #379, #153, #168, #6, #724.

Added new config option 'load-chunk-on-request' in bukkit.yml.

This will be set to true by default until I fix all chunkloading issues
with this flag off.
Note: If you are experiencing performance issues and do not need any
chunks force-loaded, try disabling this setting.

* Added loadChunkOnProvideRequest for transferPlayerToDimension to fix
issues such as Twilight Forest's teleport not loading chunks properly
before spawn.
fixes and tmp logging stuff
More "proper" fix for all the fun chunk loader issues
