Update to 2018_v4 image and new build system. (#598)

* Revert "Force OpenCV to 3.1.0 (#602)" This reverts commit 50ed55e8e2. * Removes Simulation * Removes old build system * Removes old gtest * Adds new gmock and gtest * Updates to new ni-libraries * removes MyRobot (to be replaced) * moves files to new location * Adds new sim backend and new test executables * updates .styleguide and .gitignore * Changes cpp WPILibVersion to a function MSVC throws an AV with the old version. * Disables USBCamera on all systems except for linux * 2018 NI Libraries * New build system
