(#153) Images.filter()

[llorllale]

This PR is for #153:

• Sketch of Images.filter() in ListedImages
• Left puzzle for implementing integration tests for RtImages.filter()

I'm also not so sure what the merge strategy should be for these filters. This PR will simply substitute any previously specified filter's values, but I'm not sure if you wanted to actually merge the values of the filters.

Job #160 is now in scope, role is REV

[0crat]

@amihaiemil/z everybody who has role REV is banned at #160; I won't be able to assign anyone automatically; consider assigning someone manually (as in §19), or invite more people (as in §51), or remove the job from the scope (as in §14)

@llorllale looks ok, thanks! Yes, I want filters to be merged. That is, if you call Images.filter(...) times, then the final instance of Images should respect all the specified filters.
