Added new API to record and play events
Added examples illustrating functionality

* Add a function to clone a sound and share data with another sound.

* rename items based on feedback

* PR Feedback, use custom unload for sound alias, not variant of normal sound unloading

* sound_multi example

It was quite restrictive and hacky implementation, just load multiple types same sound to play multiple instances.

Moved to raudio library repo: https://github.com/raysan5/raudio

REMOVED: core_basic_window.cpp

NOTE: When building for 64bit in raylib static mode, CloseWindow() symbol collides with user32.lib symbol. No solution for that at the moment, just compile raylib as shared library (raylib.dll), actually it can be chosen on project configurations.
