Fix formatting of /warps (WarpList) to add spaces between them
Fixes #71 and #72

help for single command name now prints description and tooltip.

reload will not attempt to load some crazy-ass world names anymore.
Workings on Permissions

* Extracted an interface from PermissionProvider to allow multiple
and eventually plugin-level exchangable permission provider implementations

* refined permission lookup again so hasPath will take into account asterisks,
which it wasn't doing, possibly causing derplings

* Rewrote the addPath algo to be a bit more effective
Removed isLibrary property from plugin jars

It's basically useless. In order to avoid having the classpath in a plugins manifest,
the library will still require to be loaded by CanaryClassLoader.
And when that happens, we can aswell execute dependency resolving for it too.
Fixed another derp in PermissionProvider
Giving no prefix to playermod prefix will remove it
Attempt to fix dupe exception bug in CommandManager

Also added back making subcommands from other classes / already loaded commands
Revamped help System a little

There is now only one HelpNode for each command, that knows all aliases.
Saves some memory.
Also allows for grouping help context so there won't be
2 pages of help context telling the same thing for x different aliases of a command.
Help will now display a list of all known aliases instead.
Changes to player and group prefix handling

We no longer expect the first char of a prefix to be a colour.
Changes in some command related things

playermod permission check will now take into account permissions inherited from any groups

playermod group check will now require 3 arguments min to prevent AIOOBEs
Added possibility to set others homes to /sethome
Updated some Javadocs
