move v8 src to google dir
moving v8 source into main extension
move google upstream source dir into v8 ext dir
include v8 library in generated bundle
prep for 0.4.7
roll the upstream build into the main extension build
Documentation was confusing the gem packager.
simplify build instructions with bundled v8.
Only install scons and build v8 if it has not been built already.
Missing CVS.py from the scons library due to ignore patterns.
Don't need libv8 anymore, only python 2.5 which is required to build it.
