Bug#931252: lximage-qt: should have a manpage

[Alf Gaida]

If you want a manpage - just write one. We will be happy to merge it 
upstream. There will not be a manpage stub for debian.

Re: Mandatory - of course i could use a tool to convert the help into a 
manpage, but: Really, no! Never ever. Never. Really. It will be more 
likely that the hell will freeze over.

Cheers Alf
