build system

added a build system, currently very basic

from left to right

log and panel changes what will be placed 

p is for place places selected object

r is for reset rotation resets cursor rotation

<> rotate forward/back still need to work on this so player facing direction gets put into account

the bending arrows <> rotate around the heading swivels it

the up down arrows rotate left to right , needs to be affected by facing direction has well

the up down left right arrows control position/location of cursor

U is up moves the cursor up

D is down moves the cursor down

0 and 1 those set the increment press 1 it increments by 2 and 0 it increments by 1

these affect position of cursor movement, 

sidenote probably should rename 0 and 1 to 1 and 2
