* added vector.rotate
* added vector.forward_from_rotation and vector.up_from_rotation
* added vector.forward_up_to_rotatiton
* fixed some bugs and formatting with vector functions
* shortened name of some new vector functions and added documentation
* made vector.rotate not require a unit vector as axis
* fixed crash with vector.forward_up_to_rot
* renamed new vector functions, made vector.rotate apply a rotation matrix, old vector.rotate is now called vector.rotate_around_axis
* documented vector function changes
* removed some whitespace to appease luacheck
* implemented and fixed optimization of vector.rotate_around_axis by SmallJoker
* added some unit tests for rotation vector functions
* clarified that rotation vectors are in radians and according to the left hand rule
* hopefully appeased luacheck
* renamed rotation_to_horizontal to forward_at_rotation, rotation_to_vertical to up_at_rotation
* handled cases where sin or cos are 0 in rotation vector functions
* added more comments
* clarified documentation of rotation vector functions
* added more unit tests
* changed way in which vector.rotate_around_axis is adjusted for left handed coordinate systems
* made vector.rotate_around_axis actually left handed
* unrolled matrix multiplication
* removed vector.forward_at_rotation and vector.up_at_rotation
* prettified vector.rotate_around_axis, made previous commits not break anything
* removed references to removed vector.forward_at_rotation and vector.up_at_rotation
* removed documentation of removed vector functions
* clarified documentation and fixed styling of rotation vector functions
* restyled comments minorly
* spelling fixes and some hopefully better comments
* allowed 'up' to be missing from vector.directions_to_rotation and removed requirement for unit vectors as arguments
* made vector.rotate_around_axis() right handed again for consistency
* documented previous changes
* made matrix multiplication actually multiply
* renamed vector.directions_to_rotation() to vector.dir_to_rotation()
* optimized a distance comparison
* Fixed potential false positive in unit tests.

automatic_rotate does not make sense if it is absolute. Make it relative.
To avoid bouncing, set_rotation did not update the client when automatic_rotate was set. That's no longer necessary because the new spinning method applies the rotation on top of the current one, and the updates are necessary for set_rotation to actually transform the object.

This adds support for optional “off state” icons for statbars. “off state icons” can be used to denote the lack of something, like missing hearts or bubbles.
Add "off state" textures to the builtin statbars.

New formspec elements:
- `scroll_container[<X>,<Y>;<W>,<H>;<scrollbar name>;<orientation>;<scroll factor>]`
- `scroll_container_end[]`
Other elements can be embedded in this element. Scrollbar must be placed manually.
