Several minor fixes:

- Added part of Austin's msvc8 fixes (vector::erase function
  was "misused"), hopefully compiles better now.
- Ctrl-b now also bakes a selected fluidsim domain
  similar to the softbodies.
- Added surface smoothing option for domains: default is
  1, higher values result in a smoother surface (and probably
  slightly higher comupation times), while 0 means the surface
  is not modified at all.
- Added BLENDER_ELBEEMBOBJABORT environment variable in readBobj,
  if >0 quits blender when a not yet existing fluidsim
  frame should be loaded. Useful for rendering simulations
  as far as possible from the command line.
- Surface normals pointer is now set to NULL in readfile.c
- Fixed win32 error string handling, now uses a function
  to return the string from the solver.
- Fixed fluidsim particle halo scaling problem.
- Solver update
