LibGL: Implement glIsTexture

Browse source 
Required by Xash3D for the r_showtextures command, where it shows every
allocated texture on screen.

Description of glIsTexture from the spec:
"glIsTexture returns GL_TRUE if texture is currently the name of a
texture. If texture is zero, or is a non-zero value that is not
currently the name of a texture, or if an error occurs, glIsTexture
returns GL_FALSE.

A name returned by glGenTextures, but not yet associated with a texture
by calling glBindTexture, is not the name of a texture."
