full-picture with space in filename does not render

full-picture with space in filename does not render
In a gallery settings.yaml, the image with filename test pic.jpg does not render in the browser. There's just a gray background.

sections:
    - type: full-picture
      image: test pic.jpg

It works if the space is removed (and the underlying file appropriately renamed).

sections:
    - type: full-picture
      image: test-pic.jpg

I'm a bit at a loss with this one. No idea what's causing it.

After working on #116 I see there are multiple areas in the code with such issues. In general it is assumed that paths, not just filenames, won't contain whitespaces, which is a silly assumption and needs fixing.

I noticed the same: Prosopopee doesn't lay well with spaces in file names.

I've a similar issue when building where directory name contain space.
