Vega Strike Code

All case statements in main src folder and in src/cmd and all its sub-folders checked for possible uncrustify bugs. None found so far. All changes committed are cosmetic.

Bug in ani_texture.cpp that caused the loss of starting splash screens and billboards around stars squashed. Credits to Safemode for the find. A debugging line removed from animation.cpp.

had forgotten to commit unit_server.

Sorry, forgot something important in the cs_xxx.h files; they could undefine symbols erroneously if a file was included twice.

had forgotten to commit cs_boostpython class. Other changes are cosmetic.

Fixed a mistake I made in merging techniques. Fixed a few more macros. Removed use of abs() with pImage->ecm, which is unsigned. Also simplified some of the logic that uses ecm, to reflect the fact that it can't be negative.

Merged Klauss' commit for premult alpha blend mode (r12630) onto the reformat branch.

Hunted for unsafe macros, one folder at a time. Gone through the main /src folder, and subfolders /gfx,
/cmd/ai and /cmd/collide2. Probably about 100 macros have been wrapped in do{}while(0). A problem
with vegaserver about it not being able to load the universe seems to have been fixed.

* wrapped a few more macros in do{}while(0)'s
* removed #include "unit.cpp" from unit.h; added #include "unit.h" to unit.cpp
* made it work :) unit.cpp now compiles to its own object file, for both vegastrike and vegaserver
* had to add a few <xxx>_server.cpp files, and modify the Makefile.am lists quite a bit
* re-uncrustified all changed files
