Title: Allow boost to be build with system layout.

Hi there, this is my first pull request to anything, ever, so I really hope I didn't do anything crazy.
I modified the boost install formula to have a new option: `--system-layout` which will build and link all boost libraries with their base names, rather than being tagged by their attributes. I believe this is the current default build configuration for boost.

I hope it looks OK!
Thanks,
Murphy
