apothecary recipe for glew 1.11.0

This adds support for the latest version of GLEW and the latest methods in OpenGL.

- [x] windows visual studio 2012
- [ ] os x (needs testing) 
- [x] linux (provided via package manager / external dependencies ?!)

This also fixes the previously broken upgrade routine for vs2010 project files. 

GLEW 1.11.0 comes with a native VS2013 solution, so updating the vs recipe once we've switched over to vs2013 should be trivial.

Note that I have left the updated binaries / headers out as not to fatten the repo unnecessarily, but tested them successfully.

**make sure to run apothecary on all platforms before creating the distribution packages**
