Removed dependency on libboost-regex.

It was kind of silly to pull in the entire lib for exactly one regular expression.

 EmulationStation uses some C++11 code, which means you'll need to install at least g++-4.7 on Linux, or VS2010 on Windows. 
 For installing and switching to g++-4.7 see [here](http://lektiondestages.blogspot.de/2013/05/installing-and-switching-gccg-versions.html).  You can also just use `export CXX=g++-4.7` to explicitly specify the compiler for CMake (make sure you delete your CMake cache files if it's not working).
 
-EmulationStation has a few dependencies. For building, you'll need SDL2, Boost (System, Filesystem, Regex, DateTime), FreeImage, FreeType, Eigen3, and cURL.
