    docs: Fix missing Properties and Signals sections in reference
    
    gtkdoc module didn't find the types file. As a side effect, 2 files have
    a different name, hyperlinks are working:
    
    totem-TotemObject.html → TotemObject.html
    totem-BaconVideoWidget.html → BaconVideoWidget.html
    
    Closes: #368
