Spe - 0.5.1.A

Hi,

you are doing a good job with Spe. I like it.

I usually work on linunx and i find the MDI interface to be the best. 
The SDI is too confusing.

Just a couple of things:
- scrolling with the mousewheel doesn't work on the editor, but it works 
with the shell. This wa true also with previous releases.
- i think there is an error in the startup script for linux 
(/usr/bin/spe): the first line is #!C:\...\spe.exe

Thanks.
Mattia.
