Update ambuild tooling to work on both Windows / Linux with boost distrib (#3)

* Add Windows / msvc boost support on AMBuild

* Disable RTTI and use config on b2's side

* Update AMBuild to require boost's setup on Windows / Linux

* Remove HL2SDK and MM:S settings in configure/buildscript

* Indenting is hard
