improve or remove pattern factories

[AEnterprise]

while the concept of the pattern factories is nice they are not usable at the moment for multiblocks that consist out of multiple blocks

we eighter need to be able to merge patterns next to each other (put one on the left/right/top/bottom of another pattern) or remove it, without the ability to add them next to each other the factories are only usefull for the very simple patters

pinging @MrKickkiller : can you do that as you made them in the first place or should i do it?

though i would prefer to just improve them instead of removing them as that would make defining multiblock structures alot easier
