rename inkstitch/ to lib/

You can't have a module and a package named the same thing.  PyInstaller wants
to import the main script as if it were a module, and this doesn't work unless
there's no directory of the same name with a __init__.py in it.

+    The user wants the machine to pause after this patch.  This can

+    normally would not stop between colors.
+
+    On such machines, the user assigns needles to the colors in the
+    design before starting stitching.  C01, C02, etc are normal
+    needles, but C00 is special.  For a block of stitches assigned
+    to C00, the machine will continue sewing with the last color it
+    had and pause after it completes the C00 block.
+
+    That means we need to introduce an artificial color change
+    shortly before the current stitch so that the user can set that
+    to C00.  We'll go back 3 stitches and do that:
