Add possibility to load themes from profile directories.

Themes are now loaded from the following directories:
 1. Directory "themes" in user profile
 2. Directory "themes" in root profile directory
 3. System data path
      > /usr/share/qupzilla/themes on Linux
      > $EXECUTABLE_DIR/themes on Windows

Closes #928
