[Kalzium] Idea for some new info: applications

[Kristof Bal]

Hi all

I'm thinking of adding some extra info to Kalzium (for the "Misc" tab): 
applications. This part basically tells something about the elements' usage.
For example: Hydrogen
Applications: Processing of fossil fuels, nuclear fusion, energy 
carrier, rocket fuel... ...and some others I can't think of right now :)

It shouldn't be that long (say, max 5 items), and many of the elements 
with a higher number don't have one, so that also saves work (and 
translation).

It also won't take much time to implement, just modify detailinfodlg.cpp 
and elements.xml, so even I can (and want to) do that.

Regards
Kristof
