A more versatile exp multiplier system

[eq4me]

I pondered this for some time but dont have the time to implement this:

It would be nice to have a more versatile EXP multiplier system.

Imagine you want to run a server where people initially level very fast but getting slower the higher level they become.
So it would be nice to assign an multiplier to an level range. Below an example of what I have in mind:

A table with two unsigned init entries.

level;multiplier
1;8
10;5
30;3
50;2
60;1

So at level 1 you have an 8x EXP multiplier which goes down linear to 5x at level 10 and goes further down to 3x at level 30 and so on.
If someone just wants to have an fixed multiplier he just sets his desired multiplier at level 1 and adds no further rows.

Edit: The same might be cool to have for AAs.
