[Texmacs-dev] Update of documentation on svn

[Corcelle]

I've just 
 - added the documentation for the Asymptote plugin in :
     trunk/doc/about/authors/plugins.en.tm
     trunk/doc/plugins/asymtote/
     trunk/doc/plugins/asymtote/asymtote-web.en.tm
     trunk/doc/web/plugins/graphics.en.tm
     trunk/doc/web/plugins/plugins.en.tm
 - corrected Eikleides to Eukleides in the 
"trunk/doc/about/authors/plugins.en.tm" 
 - completed the documentation for Eukleides plugin in :
     trunk/doc/plugins/eukleides/eukleides-web.en.tm

Hope I didn't do anything wrong.

Best regards.
