cmd_area_attack_tweak.lua: remove all but 1 CTRL+Area_Attack's attack queue when user append extra order with SHIFT

This it to make CTRL+Area_attack behaviour consistent with bomber_command behaviour.
cmd_area_attack_tweak.lua: undo adding "internal" tag to attack command (no need at the moment)
Finished removing firing frame tracking from Outlaw script.
Pheonix sleeps 400 ms (from 200) before reloading

This should let it hit static targets reliably, particularly in light of
it's turn speed buff.

cmd_area_attack_tweak.lua: make CTRL+Area_attack consistent with bomber behaviour
Added a gadget to use AllowBuilderHoldFire. Currently hold fire is never allowed because SetTarget can be used to workaround the temporary hold fire. If anyone wants to nerf comms a bit they could investigate making SetTarget listen to AllowBuilderHoldFire.
VERSION{v1.2.6.20}
Stable for some small fixes:
 * Repair speed fix.
 * Slasher fire while moving fix and suspension fix.
 * Fixed Scorcher suspension script.
 * Split area attack works well when orders are queued after it.
 * Fixed Pheonix aiming.
 * Fixed metal map view on bumpy maps (Issue 12).
