add params for "TRIM after" and "STOP after" (#29)

  * adds new options to Params: "TRIM after" and "STOP after"
  * adds tooltip support to Params
  * inkstitch now includes libembroidery and can directly output any supported file type
    * this avoids the need for `libembroidery-convert` and compiling embroidermodder!
  * TRIM support for DST format (inserts 3 JUMPs)
  * STOP command supported as an extra color change that the operator can assign to code C00
  * TRIMs cause the following jump stitch not to be displayed in the Embroidery layer
