v0.1.7

Both plugins now carry proper help text, which Resolume shows you in its interface.

Vectrix's description used to be a caption — "Vector CRT synth: oscillator, pedals, oscilloscope" — where Resolume's own effects use that same field to explain what a thing is and how it works. Its CRT effect spends two paragraphs on it. 110 of the effects that ship with Arena have one.

Both plugins now explain what they are, the one idea everything rests on (brightness follows dwell time — where the beam moves fast the trace is dim, where it turns around it blooms), and that the panel only shows the controls that can currently do something, which is otherwise a surprising thing to run into.

Nothing about the picture changed.

On tooltips

Requested in #8. Per-parameter tooltips are not available to any Resolume plugin — the interface has no channel for them. This is the closest thing that exists, and it is most of what was being asked for. Thanks to @VJPandaAU for the request.
