It seems that there are request in the form
"blob://foo.zim/<uuid>".
I don't know where it come from, we cannot handle it and even Qt is parsing
it wrongly (scheme and host are empty, path is the full url request).
By using a string to handle the url, it is simpler to change "http://" to
"zim://".
This is a first "more than alpha" version of kiwix-desktop.
It takes a zim as command line argument and open it.
There is no navigation button, and the adresse bar is read only.
It crashes if no zim is given on the command line.
