Attempt to fix a potential name conflict between Freestyle and the compositor.
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).

Apparently a name conflict between the two Blender modules is taking place.
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.
