[pitivi: 2/3] Add more keyboard accelerators

[Edward Hervey <edwardrv src gnome org>]

commit 133f85cf06f11e1c438cab19ddbf7aa5cd3a1670

    Add more keyboard accelerators
    
    Make Ctrl++ the default ZoomIn accelerator, but still allow
    zooming in with Ctrl+= (convenient for USA keyboard
    layout) by adding an additional action for that.
    Fixes #609325
    
    Also add additional actions for zooming in/out with
    Ctrl+KP_Add/Ctrl+KP_Subtract
