Close #1688 : Transform the moving window velocity to its boosted-frame value. (#1700)
* Source/Utils/WarpXMovingWindow.cpp : Transform 'moving_window_v' to that in the boosted frame '(moving_window_v-beta_boost*c)/(1-moving_window_v/c*beta_boost)'.
Examples/Tests/moving_window_boost : A simple test gives the moving window velocity in the boosted frame.
* Remove test
