- combined frame and variable view into a single table

- make_var now sets up all back pointers, so we don't crash when deselecting a
  variable (this bug was uncovered by cleanup in the previous commit)
- report_parse_error didn't print a newline at the end of the message
- introduced frame reference selection and the data structures needed for it
- bounding box calculation of arcs used x for y
- added frame reference selection example quad.fpd
