BinDeps work

Don't merge yet, it's not working and incomplete. 

@loladiro: I'm having trouble with this build script. I might be doing something wrong with the Autotools provider, but can't figure it out. The build fails with:

```
====================================[ ERROR: NLopt ]====================================

File  was not created successfully (Tried to run SynchronousStepCollection({`make -j8`},"","") )
at /home/mlubin/.julia/NLopt/deps/build.jl:13

========================================================================================
```

For some reason it's never running ``make install``?
