XHP (help pages) code snippets for KDE editors

Hi

I made public in the wiki a set of XHP (help pages) code snippets for
KDE editors (KTextEditors) available in Kate and KDevelop.

The snippets, some simple, other more complex, will reduce typing effort
and possibly prevent errors when assigning attributes, notably the id=
attribute that must be unique in a xhp page.

Details in the wiki page:

Enjoy !
