[boost] autoconf-like configure on RC_1_33_0 branch

I've placed an autoconf-like "configure" script on the RC_1_33_0 branch. If you're a *nix user and would like an alternative to directly using bjam, give it a try and send me some bug reports :) Typically one would just use: ./configure --prefix=/where/to/install make make install Run "./configure --help" for more options.
