Web cleanup (#539)

* Refactor generate.py and dream.py

* config file path (models.yaml) is parsed inside Generate() to simplify
API

* Better handling of keyboard interrupts in file loading mode vs
interactive

* Removed oodles of unused variables.

* move nonfunctional inpainting out of the scripts directory

* fix ugly ddim tqdm formatting

* fix embiggen breakage, formatting fixes
