First commit in branch
The color in the bottom colorbar can be selected now using the arrow keys.
Changed mkstep to tmpnam, so it's cross-platform now.
Using tmpnam on Windows and mkstep on others so the compiler won't
complain about security.
Replaced mkstep and tmpnam by g_build_filename.
Removed redundant headers.
