Vega Strike Code

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.

merging safemode branch -r12658, return unit.h/.cpp changes back to pre-merge state.

fix unit changes chuck made. Apparently the vegaserver defines were root of the problem that led to the changes being reversed

merge safemode branch -r12656, merge mucking fixed. vegaserver compiles again. also, not sure how the mesher cmake setup got lost but it's back

fix merge muckup of images_server
