Vega Strike Code

No need to disable linear filtering on non-MIPped textures. Only clamp mip level.

Added logging output for successful technique compilation.
Helps to know what techniques are being used.

Use dynamic libboost_python when --with-boost=system.
My distro (and many others it seems from the reported troubles in the forum) don't ship with a libboost_python-st (static version).
I checked the repository and it's not even there.

Please, everybody that used --with-boost=system re-check your build to see if it works for you.
If not, we may need to add a --with-boost=system-static.

Add 2.6 to the list of supported versions
(yes, it works)

Changing the default optimization level from 3 back to 2, as -O3 makes vegaserver segfault.

fixed problems with stale picked lights surviving both jumping (causing memory corruption) and light deletion (causing _llights to be 'owned' by more than one entity

Added #define NOMINMAX before all "#include <windows.h>" lines, to prevent VCC producing min() and max() macros.

Got rid of all occurrences (or at least those grep was able to find) of "using namespace std", and replaced them with target specific directives, such as using std::vector; using std::string; using std::endl... A mystery remains with navcomputer.cpp, which works without using namespace std, even though it shouldn't. It's probably getting it from a header file; but I don't know which.

Sorry, I had a bug in the ambientmapped_simple.fp shader. Fixed. Plus, I finished fixing the low end -simple techniques' vertex shaders. Yellow and white ships and flickery planets should be fixed for good now.

Fixed problem of yellow ships and flickering planets, at least for a high shader (nicest) user setting; probably not yet for default setting. Also fixed mistakes I introduced for lights 2 through 7 (per-vertex lights) in highend.vp and default.vp.
