Forge the freeform redaction tool

out of the Freeform Line tool in Draw.

* Replace .uno:LineToolbox with .uno:Freeline_Unfilled in Redaction toolbar

* Add new parameters to .uno:Freeline_Unfilled
  - SfxUInt16Item Transparence, SfxStringItem Color,
    SfxUInt16Item Width, SfxBoolItem IsSticky

* Handle the params in FuConstructBezierPolygon

* Now the freeform line draw tool on the Redaction toolbar
  works with a default width of 5mm, color of COL_GRAY7,
  and a transparency of 50%; and it sticks when it is
  clicked/selected once until user deliberately deselects it
  by clicking on another tool or by clicking outside of the page.

* Known problem: icon is not displayed on the toolbar after adding the params
