[crossfire] Shortening experience bar for GTK2 client

[Kevin Zheng]

Greetings,

The GTK2 client has an experience bar at the bottom left corner in the default 
layout, right underneath the HP, Mana, Grace, and Food bars. As your character 
levels up, your experience increases (duh) as well as the experience needed 
for the next level. Both these numbers are shown next to the experience bar.

I level up, the experience bar becomes wider as the experience numbers 
increase. At some point it is wider than everything else and starts eating up 
unnecessary space. This isn't a problem on a big screen beacuse there's lots 
of space, but it's annoying on a 1024x768 screen. I don't want to switch 
client layouts, either, so here are some of my ideas:

1) Show exp with suffixes. For example, show 10K instead of 10,000, 10M 
instead of 10,000,000, and so on. Drawback: can't see small exp increments

2) Show remaining exp instead of total exp. Drawback: counts backwards

3) Show difference between current exp and next exp level. When level up, 
start counter at zero and end at next exp stage. Drawback: confusing.

Any ideas?

Thanks,
Kevin Zheng
