small bug fixes in prompt generation

Browse Source 
- fixes no closing quote in pretty-printed dream_prompt string
- removes unecessary -f switch when txt2img used

In addition, this commit does an experimental commenting-out of the
random.seed() call in the variation-generating part of ldm.dream.generator.base.
This fixes the problem of two calls that use the same seed and -v0.1
generating different images (#641). However, it does not fix the issue
of two images generated using the same seed and -VXXXXXX being
different.
