mklic.pl run to update in-client license display

* Nonfunctional change
Fix mumble_ol.dll not being versioned under windows.

* Low impact fix for RC. Directly set VERSION in overlay.pro
* Currently the version is set multiple times
  in different .pro/pri files. This should be refactored to come from
  a single .pri file (similar to /macx/common.pri) used in all locations.
* Should probably use an RC file to be able to set more information
