Adjusted persistence lib

Persistence lib update

There was a bug while removing mines, this is now possible.

When removing a mine with /mine remove <name> the affected area will be cleaned up.

adjusted plguin basic mechanics and optimize than

optimized block spawn rate
basic implementation for light source control

added glowstone with a low percentage to provide lights without using torches. Its useful for world protections which allows breaking but not placing blocks.

Ths spawn rate of each possible block was optimized so 100% are 100% now incase you dont chose other blocks!

There was a console error which was spammed when no mines has been created yet, now its gone.

Also there wont be a generating message when automatically or manually refreshing a mine

From now your mines will refresh every 60 seconds on default.

You can configure the delay in your config.yml, just put the delay in minutes to the delay section.
