[PATCH] InsetGraphics updates

[Baruch Even]

Avoid auto-converting to InsetGraphics from InsetFig (Garst's request).
Changed from GRAPHICS to Graphics.
Changed lib/configure.m4 to convert epsi figures too.

Please apply soon, the GRAPHICS to Graphics change means that the inset
loading after saving doesnt work until it is applied.
