add install_prereqs.sh

[RussTedrake]

drake001 was failing because of a missing dependency. resolved with

brew install pyqwt

fixed by RobotLocomotion/drake/pull/1287. For what it's worth, I'm not a fan of per project install_prereqs.sh, I'd rather have package manager dependencies listed in the drake.

awesome, thanks!

@RussTedrake having all of the dependencies listed at the top level in drake would also allow us to switch to Travis's newer & faster infrastructure, which means faster build times. The new infrastructure does not allow the build to use sudo, but does allow us to list all of our needed apt packages in the .travis.yml file. We need sudo right now in order to invoke all the install_prereqs scripts.

But i'd be fine if drake's superbuild could report it's list of dependencies for the currently included externals, but want to ensure that:

• the individual pods also know their externals (for use outside of drake)
• drake only lists the externals for the existing externals (i think). It seems like the list of all possible dependencies would be obnoxious. No?
