multiple zones

[shipyy]

this is a attempt at the the #403

needs to be tested thoroughly

i tried to PR to the other branch but i got weird conflicts xD, hope making another PR for it is ok

[tslashd]

I believe we've tested this with @shipyy and it was working fine but there was no way merge two zones together so the zonetypeid is the same as the zone the new one refers to.

The 2 highlighted rows are the same checkpoint zone (CP1 on left side and right side)
highlighted rows could be the wrong ones, but it definitely contains 2 zones which are separated from each other and both link to CP1

Pasting the inserts for these zones so other people can test this:
