Subject: [PATCH] Add version directives to GLSL shaders

Although not technically required, I believe it is best practice for shaders to specify which version of the GLSL spec they conform to. To quote the spec:

> Shaders should declare the version of the language they are written to.

NB: I have presumed the version is 1.10, but it should be corrected if a later version was intended.
