Trying to get gates to work

No luck yet
Removed unrequired check for ordnance box
Improved Placement System

Now uses key bind placements for all buildables
Also shows nicely formatted hint windows with controls listed
Changed all "PLAIN DOWN", 1 to just "PLAIN DOWN", since 1 is the default
anyway.
Changed the "PLAIN DOWN", 60" upon completion of build because fading it
in over 60 seconds doesn't make any sense.
