Cargo: codec 76d2a1c, kernel e652b4d, graph 0545fa9; text styles, templates, solid edges

- Text styles keep their TrueType typeface through save and reopen (codec
  reads and writes the STYLE record's ACAD extended data) (#1633)
- Unnamed shape-file entries no longer show in text style lists (#1634)
- Save As offers DWT 2018; NEW asks for the template to start from, while
  Ctrl+N and the quick-access New run QNEW with the default template (#1635)
- An edge next to an earlier fillet of the same radius rounds together with
  it (kernel); the solid stays drawn and pickable while edges are chosen
  (#1625, #1107)
- A full cache rebuild drops the B-rep cache too, so an undone fillet does
  not come back with the next edge operation (#1107)
- Selected solids in shaded styles highlight only their visible edges (#1031)
- VIEW ISO / SWISO / SEISO / NEISO / NWISO snap to the isometric corners
