attempt to implement rotation on /places commands

[syol]

Hey, since zyro's going crazy about this I thought I could give it a go; this should?? make it possible to write /places 2s arrowup -1 0 <, arrowup 0 1 v, arrowup 1 0 >, arrowup 0 -1

I picked <, > and v as keywords to have it be similar to movers, I'm not sure how you handle rotation so you might wanna edit the switch cases at line 1309

I think flip should be easy to add too
