Change: Add demo charges to unused Demo Saboteur, add unique voice lines

[commy2]

• Adds previously unused voice set to the worldbuilder only Demo General Saboteur.
• Adds Suicide ability to Demo General Saboteur
• Adds placing timed and remote demo charges ability to Demo General Saboteur -- he has voice lines specifically for that
• Animation used for placing charges is from CIA Agent. It looks neat with the Saboteur model.

Uh oh, Sabotage + placing demo charges is very wonky on buildings. Saboteur may collide with building and sabotage it instead of placing a bomb. Also, this allows Saboteur to target scaffolds and sabotage those. I think best is to remove infiltration from this Saboteur and make him a demolition unit entirely.

Camouflaged unit + suicide ability. Very sneaky.
