[added] jglfw tests
[fixed] app config has sensible window size defaults and non-null title
fixed a few things in jglfw backend. don't specify a monitor or it goes into fullscreen! (need to figure out what we want to do, best solution would be to have getters on JglfwApplicationConfiguration like we have for Lwjgl to determine screen modes and monitors)
Small corrections to MathUtil random javadoc.
Merge pull request #278 from mikijov/master
