[+] Modified how resetting of mines has worked, making both instant and gradual resets more efficient
[+] Added a bunch of new commands, so they no longer need to be done through the GUI:
- /prisonmines resetdir <bottomtotop/toptobottom> <mine/all>
- /prisonmines settp <mine>
- /prisonmines srp <percentage> <mine/all>
- /prisonmines resettype <instant/gradual> <mine/all>
