Add formats and converters for cropped PDF/EPS

With LyX configured in this way, the user would only need to:

File > New from Template > EPS.lyx (or PDF-cropped.lyx):
- insert a math inset and type in an equation, or create whatever
  content LaTeX can handle,
- view/export to cropped EPS/PDF.

This would allow for LyX to act as a "generator for includable graphics" (equations, commented graphics, etc).

This fixes bug #7839.
