Update Libzip to latest 1.9.2 (#1071)
* Libzip 1.9.2
Updated Libzip to latest version 1.9.2 and changed version number in the config.h from 1.7.3 to 1.9.2. Not sure if anything else needs to be tweaked :)
* Modified Libzip to work with Visual studio
* Update README.md
Update libzip copyright.
* Added the missing files.
I've added the missing files zipconf.h and config.h, I've missed those sorry for that!
