NetRender:

- multires cache files and image .tex cache support in dependency list
- Compare md5 of files before using a local copy (not one transfered by netrender). Could be changed to a simpler CRC if speed is an issue. The goal is not to have a strong crypto signature but just to detect outdated local files.
- Reduce slave timeout to 5 minutes (down from 30). Slaves should report at most every 30s, there's no reason for a value to be that high.
- Reorder the presentation tables on the main web page (job list is more important)
- Collapse dependency list by default on job page (only show main file and headers for other files, point cache and fluid cache)
- Slave option (default: True) to also output render log to the console (as well as the usual copy to the master)
