Added AACubeShape with stubbed collision functions
exploit symmetry of collision pairings
AACube vs Sphere and Capsule collision tests

Sphere is unit tested.
Also removed the shape collision query against Octree
merge andrew/ragdoll into some ShapeCollider work
moved some functions around
fix broken build for using unititialized const float
fixes for capsuleVsAACube() with unit tests
collision logic for capsule-side-vs-cube-face

with unit tests
merge upstream/master into andrew/ragdoll
re-enabling legacy avatar-vs-voxel collisions

so that I don't break anything when this merges with upstream
merge upstream/master into andrew/ragdoll
fix whitespace formatting of curly braces
the command:

cmake . -GXcode

creates a CMakeFiles direcory in the test directory, causing the creation of the xcode files to fail with an the source directory does not contain a CMakeList.txt file.

This patch updates the CMakeList.txt file in the test directory to ignore that created dir.
This patch updates Application::updateLocationInServer()  in Application.cpp

The online status is updated when the position is send to the data web, a avatar gets an offline status if the data web did not get an update in the last 30 seconds.
This function had an LastLocationObject in which only send in the location info to the data web in case the location changed.

Removed the last location so the position of the avatar is send to the data web every 5 seconds, so that the online status remains online if the avatar is still online and does not switch to offline when the avatar does not move.
This patch updates the MyAvatar.cpp file.

It adds a check MyAvatar::goToLocationFromResponse to see if the user is online, if the teleport to the avatar is done and if not a message is shown which said that the user is not online
