Shaderjoy 1.25

@khayoz

The OpenLibrary() path is wrong. It should be simply "arexx.class" instead of "classes/arexx.class" (there is no classes directory under CLASSES:).

It only works if the class is already loaded in memory because then the path is ignored.

Thanks. Code was using OpenClass but with a wrong path. Should be fixed for the next release.

1.25 is available on http://capehill.kapsi.fi . Changes:

- Add keyboard channel. Also remove some keyboard shortcuts to avoid conflicts.
- Add projects files (.sjp) for those example shaders that require textures.
- Replace text buttons with more compact images.
- Show busy pointer during shader compilation.
- Disable uninitialized variable check (in icon) due to glCompileShader issue with some shaders:
future ogles2.library should fix this.
- Fix loading of arexx.class.
- Fix busy looping of ChannelWindows.
- Refactor some GUI code.
