Release 5

• SampleFrom is more powerful now: you can make sure you sample the same thing in certain places or make sure you don't sample the same thing in certain places.
• banks can take dictionaries and SampleFrom can specify which key (field) of that dictionary to sample.
• Options can have resources
• feedback can be a Page
• Page and Option text can be made of a list of strings and/or SampleFrom objects.
• Backwards incompatible: tags are dictionaries instead of lists now, making the tags argument to speriment-output unnecessary
• criterion available on all Blocks, not just those that contain Pages

Edit: patched the npm package so it will install the css file.
