PATCH: UML Activity

[Alejandro Aguilar Sierra <asierra servidor unam mx>]

Hello:

This patch includes to changes against vanilla dia-0.90:

- Removed draw_round_rectangle from state.c in favour of render
  draw_rounded_rect, elliminating redundant code.

- New UML object Activity. It is very similar to a state machine
  but the nodes are draw slightly different (so internally it is
  just a type of SM). However, conceptually they are very different
  so activity deserves it's own place on the UML sheet.

Though it is against dia-0.90, it could be applied against dia-cvs
without too much work, since there are few changes and a new file
(activity.xpm).

If you include this patch in the cvs, please add the changelog entry.

Regards.
