Add 'silent-rules' to automake setup in configure.ac

This is awesome, and I don't know why we haven't already done this. It
gives us the much more less verbose make output in a few different ways:

* If you run `make V=0`, you will get the quiet output.
* If you run `./configure --enable-silent-rules`, the quiet output is
  the default; verbose output can be had by passing V=1 to make.
