[sldev] Chat and IM Line History - Patch

[Zi Ree]

Hi SL-Developers!

Today I started digging deeper into the code of the Second Life Viewer, and to 
make myself familiar with how it works, I decided to implement a small pet 
feature of mine: chat line history. Coming from the Linux and IRC background 
I desperately need a way to recall my previously written lines, without 
having to copy & paste them from some scrollback buffer. So I loaded the 
Viewer source into my favourite project tool and started to work on the code.

It took me about half a day to get it done, and I hope it doe swork on other 
people’s machines, too. I decided to go for CTRL UP / CTRL DOWN as history 
recall keys, because the normal cursor keys are used for walking when the 
chat line is empty, and thus are out of the question.

Please try my patch and tell me if it worked for you or if I messed up 
somewhere :)

Have fun!
