Working on making the EvoGrid code is more configurable. Moving out previously hard coded strings to configuration files and functions.

Tried to find a commonly used library for C that will handle .ini or other configuration files, but didn't find one. libconfig0 is available in Debian oldstable, and libconfig8 is available in testing, but nothing in stable. Also, libconfig8 uses it's own heirachal format, not the common .INI format.
