Boomerang Home

BHome-1.4
Fixed players not spawning at X + 0.5 and Z + 0.5 of the target location.

Added config.yml option 'spawn_height' to enable specifying height above block player should spawn at target location.

Added updating timestamp of player's home yml file on player join in order to record last join. This enables easily identifying old player files.

Added subcommands to bhome: 'show' and 'tp' with tab-completion to allow ops to list and teleport to offline player homes.

Updated 'sethome' command so that if no home exists for the calling player and no arguments are given, a defaullt home 'home' is created.

Updated 'home' command so that if a calling player has only one home, that home is select and teleported to by default.

* Fixed problem with locations not calculating right having to do with offsets from negative coords.

NoSuchElementException at onCommand(Home.java:67 when /home is used but player has not set a home yet.
