draft solution -- for review only -- do not merge!

@haf while this is not valid Ruby (which I do not master), this will hopefully allow you to get the ideas of the proposed solution. Your comments are appreciated. 
the properties are feeded into the tool as a list of string. You want to generate:

`... --parameter "page-description" "F# Suave" "page-author" "Ademar Gonzalez, Henrik Feldt" ...`

this should be save for all platforms.
