#15 Slide API procedure

[JakobWelner]

API version of the draggerContext slider function to
speed up the workflow.
Needs one procedure which can take care of every
context dragger we might come up with, so it would
need alot of indput values to set it all up, maybe like:

- vector array containing normal vectors (LMB slides)
- vector array containing sideways vectors (MMB slides)
- default values for multiplyers (the one you multiply the
slide values with, to speed up the sliding)
- default slide values (like the one you multiply the
vectors with, to get the new position)
- start position of each component.
- (component type)
- string array containing the name of each component to
move - must be same size as the to top inputs.

Try to make it keep the original UV's as the current MEL
slider dosn't (MJPolyTools does)
