kdeaddons documentation

[Charles Samuels]

In the kdeaddons module, the documentation is arranged like so:

doc/kate-plugins/openheader.docbook
doc/kate-plugins/projectmanager.docbook
doc/kate-plugins/textfilter.docbook
doc/kate-plugins/xmltools.docbook

I propose that we change it to:

doc/kate-plugins/openheader/index.docbook
doc/kate-plugins/projectmanager/index.docbook
doc/kate-plugins/textfilter/index.docbook
doc/kate-plugins/xmltools/index.docbook

First of all, it's consistent with every other module, and secondly, and most 
importantly, it allows installing only one of the docbook files, the one that 
you actually want.
