[FEATURE] Ability to control agent tasking more granularly

[Console]

I'm currently implementing htpsy as a centralised cracking solution for our group but while we have a cracking farm that I've no problem downloading multi-GB sized dictionaries to as they're all local lan, we also have 10-20 laptops with discrete GPU's that users want to throw into the mix.

Unfortunately we're having to juggle the "secret" flag and be quick with the unassign button right now to prevent agents from reporting in and being tasked with say a 15GB crackstation dict download over a 512k hotel wifi connection.

It would be nice to be able to have more control over tasking such as...

• Agents marked as "manual assignment only"
• Agents able to set a "maximum acceptable download size" and the auto-tasking be smart enough to allocate other tasks than allocate ones that exceed that file size.

Yes I understand that this doesn't take account of the edge case of the file already existing but maybe this could be a check done on the client side too.

"You need xyz files"
"okay I have x and y but need to download 20GB of Z"
"Nope... that exceeds your download limits, task rejected, new task found".

All in all not quite sure how to go about it but having more tasking control would be a boon.
