A couple of smaller fixes;

- Modifier Panel, name label for "Virtual" modifiers was too short
- On extrude Bones, "soft distance" now is always set based on length
  of the bone (also on CTRL+click, also when Envelope drawmode is not set)
- Added undo-push for "Apply Bone Envelopees to VertexGroup" in WeightPaint.
- Menu-buttons in floating panels sometimes gave drawing error
- InfoWindow buttons were always allocated & drawn, even when window was
  zero sized... waste of cpu, tsk!
