gfm7 ~shader_error_messages

GFM7 is a fork of gfm v.7 to keep functionality that has been removed in gfm v.8

IMPORTANT: Bolt-on replacement for gfm v.7.0.8 is gfm7 v0.9.9

Unfortunately I added tag v1.0.0 for another version of gfm7 that is non compatible to vanilla gfm v7. So I added tag v0.9.9 for vanilla version of gfm v7.0.8

gfm7 v1.0.0 has breaking change - the only difference to original gfm is that OpenGL related classes ctors do not take OpenGL as its first parameters because it makes their using simpler. So instead of:

	auto program = new GLProgram(gl, shaderSources);

you can write:

	auto program = new GLProgram(shaderSources);

All error reporting is fully functionable, excluding some log messages (not errors). GLRenderBuffer, GLShader, GLUniform, GLAttribute, GLProgram have method logger(Logger l) that allows to set a logger to get functionality fully equal to original gfm v.7:

	auto program = new GLProgram(shaderSources);
	program.logger = yourLogger;
