A crash in the Freestyle renderer was reported by Ton on IRC with a stack trace below. Note that #2 is in Freestyle, whereas #1 is in the compositor. The problem was observed in a debug build on OS X 10.7 (gcc 4.2, openmp disabled, no llvm). ---------------------------------------------------------------------- Program received signal EXC_BAD_ACCESS, Could not access memory.

The present commit hence intends to address it by putting all the Freestyle C++ classes in the namespace 'Freestyle'. This revision will also prevent potential name conflicts with other Blender modules in the future. Special thanks to Lukas Toenne for the help with C++ namespace.
