Add option for dedicated jumppads

It would be nice, if the first non-named section of a jumppad definition would be the general definition of this material of jumppad. Every following section of the same material can be ignored if unnamed, but if its named, it will give you the possibility of a different configuration for SPECIFIC jumppads. So if I need 20 Jumppads in the lobby I can set them each to the same config like before, or give them a name to differentiate them from each other. Also then it would make much more sense if one could set the x and y direction in which the player should be launched in. If thats only over the config it should be fine as well, the only command that would have to be added would be the one to change a launchpad from default to the "named" section one.

I hope its clear what I mean and If you don't have time to implement it I am probably willed to do it myself :) There really is no good launchpad plugin out there anymore that doesn't use armorstands anymore so we just might improve what we got ^^
