Title: Some tweaks for improved performance in heavy-load scenarios

- made convert reject all frames but the first in animated GIFs
- made convert use JPEG size hinting for faster conversion of large files
- added nice -n 10 to the convert invocation so it doesn't compete with Apache & co. for the CPU cycles
