added configurable quest reward option in config file

bunch of debugging, lots of crash testing, still expecting possible bugs or crashes, so please notify me if you have issues

Now bigger builds are requested, also biome based blocks.

GUI now works well, there is now a quest button in trade GUI that switches to quest GUI

Set the height limit for builds

bunch of bug fixes added a bit of life into the code

please report any problems

recoded almost all aspects of the mod, now feels more natural expect crashes (please report them if you get them)
