Test adding CEF to travis.yml
Finallized changes to travis.yml
Merge branch 'develop' of https://github.com/adam4813/Sigma into develop
Changes to Sigma build flags for CEF
Added back the CEF wrapper build
Changed link dir for CEF.
Add FindGLM module and added the respecting FIND_PACKAGE to CMakeLists
Fixed the latest GLM breaking things

The latest GLM removes some implicit casting to glm::vec3 so it is now explicitly done.
Also glm::mul() is no longer available so changed line 666 in OpenGLSystem to use the * operator instead.

Also added a missing include to <iostream> in GLCubeSpehre.
Edited the README section to have stuff placed in the slightly more predictable location
Also added back the what should be the bin dir to the link path, in the off chance that it actually works
Merge pull request #139 from Meisaka/develop

CEF in travis
Merge pull request #136 from Zardoz89/log

Added a Logger to Sigma, that can outputs to std::cout or any other ...
Replaced all std::cout and std::cerr log messages to calls to Logger.
Also, fixed Logger bug, moving static globar var to static private variables inside of Log::Print class
