prevent throttling on different links

[ScuffedNewt]

adds a url to the throttle key so users arent limited from preforming different actions
also adds an exemption to admin routes

why?

• this feature is intended to stop spamming, a blanket limit (especially at 10 seconds) can be inhibiting on a click / request heaving application like lorekeeper
• admin routes have similar reasoning to the above, and are at lower risk of spamming being an issue

To be honest, this is a necessary and welcome change cause I tend to open multiple things in tabs and rapid fire approve when I'm doing approvals... and I think you can guess the problem.

So thanks, Newt!
