Bulk changing priority levels?

[alganza]

Feature request: It'd be nice if one could change the priority level of all files which have a certain level to a new one at once. For example, I'd like to make all files with "normal" (0) priority to be "low" (-10) or "very low" (-20) in priority.

Also, it'd be nice to be able to change the default priority new downloading files get when added.

It'd also be cool if the "named" priority levels (very low, low, normal, high, very high) could be edited. I now I can use numbers in between, but I'd rather have a "extremely high" or something rather than numbers. :-)
