Xmaxima ready for RC4



Hi,
I beleive I have fixed the bugs reported for Xmaxima in RC3:

1- Lisp mode now works as in Maxima.
2- "? something" also works as in Maxima (no ; or $ required)
3- PageUp, PageDown, Home, End, Ctrl-p, Ctrl-n and other key
   sequences are working again.
4- The Manual now looks much better in Xmaxima's browser (thanks
   to David May who sent us a patch).
5- Figures are now shown in the non-English versions of the manual.

Regards,
Jaime
