Feature/windows portable

[jely2002]

Adds support for a portable mode. Whenever the "ovd-portable" directory is detected next to the executable it will switch to this mode. Switching to the mode means that any files the app would normally drop in %appdata% now is put in the "ovd-portable" directory.

The system will still be touched by PyInstaller but this is for now unavoidable, when the process exits the files will be removed from the temporary directory on the system.

Closes #577.
