logic: more wstring usages

* removed header paths from VS Project setup message since VS doesn't send these anymore
* implemented using wstring in IDE communication
* fixed retrieving filepaths from QtDirectoryListbox that contain special characters
* use wstring for source extensions
* added special character as file extension to FileManagerTestSuite
