*Reorganized code so that further expansion is possible in a very organized manner.

*modpol.add_member() -- added a check if the member is already a member of that organized

*storage -- fixed bug by moving storageref to top of file

*added on_joinplayer to add players to instance

*moved minetest specific code in init.lua to modpol_minetest, organized in folders.
All overrides in one folder, all chatcommands in another, the on_joinplayer in modpol_minetest/orgs/instance.lua
