Prevent block breaks outside the border

[Warriorrrr]

Closes #87

Adds a block break event and implements it on all platforms, tested it on bukkit but not the others.

I noticed that other platforms were missing the place event so I added it to (neo)forge, couldn't find a simple way to implement it on fabric.

Looks good to me, tentatively, but will wait on merging until I have time to test this.

Looks good, pending testing, although one question: I notice there is some work done towards parity here with the various events on Fabric/Forge/Neo. This is great, however I did notice Fabric seems to be missing a place event handler. Was this overlooked, or some issue with impl there?

I couldn't find a simple way to accomplish it in fabric, so I left it out of this one hoping that somebody with better knowledge in that area might add it in the future.

I've tested this on fabric/forge/neoforge now and they all pass, I did the following steps each time:

• op myself
• chunky center
• chunky radius 10
• chunky border add
• deop
• walk to border, try breaking blocks behind it, notice it's prevented
• give myself 10 dirt, try placing it, also prevented (except fabric)
• op myself again
• able to break/place blocks as normal again
