WIP rcamera redesign vector (#2563)

* core functionality CAMERA_FREE

* fix example

* add remaining camera modes

* add view bobbing

* view bobbing

* catch curser in SetCameraMode

* adjust examples

* fix compilation on linux

* fix example text_draw_3d

* actually fix text_draw_3d

* Updated camera API

* Improve Vector3RotateByAxisAngle() function

* remove camera.mode dependency from low-level functions

* remove camera.mode from struct

* fixes after rebase

* adjust examples for new UpdateCamera function

* adjust example models_loading_m3d
