[kde-edu]: Fixes in code

[Matthias Meßmer]

Hi all!

In http://www.icefox.net/kde/tests/report.html I found:

> Invalid XML in KConfigXT files - Tests kcfg files for xml validity.

[...]

> kmplot.kcfg:12: element entry: validity error : Element entry content does 
not follow the DTD, expecting (parameter? , label? , whatsthis? , choices? , 
code? , default* , min? , max?), got (label default whatsthis )

and many more of lines like this.

As the "?" in the DTD [1] says the "missing" tags are optional. For example 
the tag <code> should even be used as seldom as possible.[2]

We should at least define the tags <label> and <whatsthis> for each <entry> 
tag.[2]
