TI Chronos emulator gets SDL interface

Thanks to Cyril Hrubis, who created .svg version of (parts of) TI Chronos display, I forced myself to create a SDL interface to chronos emulator... so you no longer have to run emulator on console and watch the ascii art.

Code is at http://sourceforge.net/projects/mychronos/ .

For now, I just did png export, and then edited each image manually -- to add transparency. I wonder if it would be possible to somehow tag subtrees in svg and then have them automatically exported as right icons..?
