I change LV624 T-comms and engineering areas (#5674)

# About the pull request

Basically I think that the little grassy area inbetween them looks a bit
shit and I wanted to kind of make the buildings two parts of the same
building and make them look alittle nicer

# Explain why it's good for the game

I think it looks quite pretty and I've made some changes to the doorwars
and stuff to make it easier to move thru the building such as removing
some of the 1x1 doorways and and clearing the "halls"


there was also some flowers on the outside of the building that kind of
weirdly overlayed onto fences making them appear broken at first glance
and I've moved those
