[gtkextra] gtk-doc update

[Stefan K. <en...@ho...>]

hi adrian,

thanks for adding me to the project. I've now commited my changes. If
the causes probelms for anybody, I am the one to blame and promisse to
fix asap.

I've also added example docs to gtksheet.c. Watch out for comments in
this format:
/**
 *
 */

The sources itself have not a lot of docs, but there is information in
the static html files you where shipping. Are they more or less
up-to-date? If so my plan is to manually copy over the docs file-by-file
and 'cvs delete' the static html file. I can't make any approximation
how long that will take as I will do that from whenever I have a free
slot. The good thing is that I learn the api by doing so and can then do
the g_object porting.

What do you think?

Stefan
