Works by detecting a collision while moving forward and then
simulating a jump. If the simulated jump is more successful,
an artificial jump key press is injected in the client.
Includes setting and key change GUI element for enabling and
disabling this feature.
* clientobject, clouds, collision, clientsimpleobject: code modernization
* use range-based for loops
* simplify some tests
* various code style fixes
* use emplace_back instead of push_back when necessary
* use auto on some iterators
* use default operator when needed
* unroll v3s16 creation on collisionMoveSimple
* C++11 patchset 9: move hardcoded init parameters to class definitions
C++11 introduced the possibility to define the default values directly in class definitions, do it on current code
Also remove some unused attributes
* CollisionInfo::bouncy
* collisionMoveResult::collides_xy
* collisionMoveResult::standing_on_unloaded
* Clouds::speed
* More constructor cleanups + some variables removal
* remove only write guiFormSpecMenu::m_old_tooltip
* move header included inside defintions in genericobject.h
* remove some unused since years exception classes
* remove unused & empty debug_stacks_init
* remove unused & empty content_nodemeta_serialize_legacy
* remove forgotten useless bool (bouncy) in collision.cpp code
