FR: Extra tracking options for Type 5 beams

So we're doing some BP brainstorming and the notion of making slash beams less random whilst still being slashy was talked about. For this particular sequence, the weapon's stats are:

+Start Position: CENTER
+Start Position Offset: 0, 0, 0.8
+End Position: CENTER
+End Position Offset: 0, 0, -0.8
+Orient Offsets to Target: TRUE
+Scale Offsets to Target: TRUE
+Per Burst Rotation: 180
+Per Burst Rotation Axis: CENTER

It looks great when the target is static! When the target is not, however, it's kinda whacky.

So our requests are:

1. A flag to ensure that type 5 beams will trace the target in the orientation it was when the beams are firing, rather then warming up.
2. A flag to ensure that type 5 beams will trace the target whilst they're slashing (eg so a beam can "follow" a target).

And at the risk of asking for slightly too much:
3. An option to randomly swap start and end positions. So a beam might sometimes fire left to right or right to left, but still reliably along the same path.

And at the risk of asking for way too much:
4. A way to tie offsets to the model's geometry rather then the radius. ATM the GTVA Colossus's model is causing a lot of problems. Given that direct beams can select a random point on the ship's geometry, this should be possible?
