Shadersave 0.4
Small release.
- Rewrite Shadertoy loader, this should fix all naming conflicts and allows some shaders to work, such as pow(The Shining, 2.0) which previously didn't work.
- Remove dependency on boost::regex.
- Clean up code.
- Remove dependency on GLM.
You may note the settings dialog has a lot more stuff, but it's disabled as it still is work in progress.
