Remove Standard WPs in special WP handler

[MiC17]

While currently still quite practical for testing purposes, you might want to remove waypoints that are otherwise accessible out of the special WP dialog.

This should aid in the quicker finding of things in the dialog, especially if searchBuilding doesn't stay your only new addition.

To possibly be removed:

• "move" (accessible by simple RClick)
• get in + get in nearest (accessible by simple RClick)
• destroy (accessible by simple RClick)
• join + leader (accessible by drag click)
• cycle (accessible by Alt + RClick)
• load (not functional as far as I can tell, can be achieved by combination of MOVE + RClicks)
• dismiss (same as double - clicking and then setting to relax, I believe?)
• unload + TR unload (not functional as far as I can tell, can be achieved by combination of MOVE + RClicks)
