qutils_demo.pro paths

[WakeRealityDev]

Hi. thank you for sharing this.

Some cleanup is needed with paths in the qutils_demo. For example, it has hard coded references to E: hard drive that is Windows specific to your system and a github checkout will not have that. https://github.com/Furkanzmc/qutils/blob/master/qutils_demo/qutils_demo.pro#L48

I have been unable to get files into correct places to run the demo. Still trying to sort it out. Thank you.
