small patch to make mipmaps under linux work

[specialtactics]

Hi,
mipmaps for textures using opengl and linux didn't work, so i changed 3 lines or so and now they do (as far as i've tested). Here is a diff of COpenGLTexture.cpp:

9a10
> #include <GL/glu.h>
26c27
< hasMipMaps = false;
---
> // hasMipMaps = false;
85c86
< #ifdef _WIN32
---
> // #ifdef _WIN32
88c89
< #endif
---
> // #endif

Then just add -lGLU to the LIBS in Makefile (both for source as well as for the examples!).

nice
Bugfixes similar to this have been posted several times I think, so I should really put out the next release soon.
