raylib modules have been slightly renamed to add some identity and note that they are independent modules that can be used as standalone separate parts of raylib if required.
The renamed modules are:
- `core` -> `rcore`
- `shapes` -> `rshapes`
- `textures` -> `rtextures`
- `text` -> `rtext`
- `models` -> `rmodels`
- `camera` -> `rcamera`
- `gestures` -> `rgestures`
- `core` -> `rcore`
All the build systems has been adapted to this change.
