Classifications: show settings, rules and data processing

[#1]

when I need to make investigations about the settings of specific classifications within one (or multiple RS) I need to check several screens (or can't even find the desired information.

common questions to answer:

- what is the classification and when was it changed

- which classification rules affect a specific item (from the classification rule builder), including history

- what manual uploads have been performed and has the data already been processed?

i kindly ask to create a screen where the admins can see more information at a glance. the above questions just give a short overview what might be interesting. I'm sure there are more information regarding the classifications which could be very useful to have in a single screen.
