Added pseudorandom initialization of bee seeds.
Fixed a type in World, and added initializations for variables in __init__.
Added Gui code to amount, seed, width, height and initialize elements. Restored the arguments function of bees.
Finished adding gui code so the initialize button causes world.prepare to be called.
Fixed some bugs in World. Now if you enter values in the gui and press initialize world.prepare is called and seems to work. Still lacks some basic sanity checking of arguments.
Added default values to amount, width, height and seed fields.
Allowed for beearguments to be passed on to bees via world.prepare.
Fixed a case-based spelling error in world.__init__
a start for a implementation of step
small updates to world and randombee
Fixed mistakes in basebee and world
