Following raylib notation rules

Added ColorFromHSV()

This specific change could be very annoying for people already using FLAG_MSAA_4X_HINT, their programs will compile correctly but window won't be shown...

Window visibility

Planning to promote raudio module as a simple and easy-to-use front-end for the amazing mini_al library, so the name change.

Name comes from raylib-audio but in spanish it also remembers to word "raudo", meaning  "very fast", an analogy that fits perfectly to the usefulness and performance of the library!

Consequently, raylib version has been bumped to 2.4-dev.

- Unsigned int not supported on OpenGL ES 2.0 -> Removed
- Reorganized enum -> Removed BOOL (not uniformType)
- Support sample2D uniform type

Shaders uniforms array

Add project/scripts

This reverts commit 1fe6d9fc06.

Because upstream GLFW now contains a fix.

glfw/glfw@5595fa3ae6 implements a proper fix for the macOS Mojave
problem of OpenGL windows not being rendered until moved or manually
updated.

Pull in the current master and rebase the three patches we have on top:
- two commits we have for reuse of the GLFW CMake build system for Wayland
It hasn't yet to be acknowledged upstream.
- one commit removing #include <windows.h> in glfw3native.h to avoid
duplicate declarations.

Fixes #655 and #665.

Move away from v1.12 as GLFW now requires >= 1.15.

The .travis.yml is getting increasingly ugly. We should maybe consider
creating separate shell scripts for each target..

Specific textures generation code is quite redundant and not flexible for the user, I'm trying to figure out some easy way to allow raylib users to do the same without needing those functions (very specific and shader dependant). RenderTexture loading and Cubemap textures support must be improved.

CMake defaults to generating a Visual Studio build on Windows,
which doesn't involve make. Thus use cmake --build to abstract
that detail away. We already do that in the appveyor.yml.

The install line is a bit hacky: cmake might not be in the search
path when using sudo, thus use "$(which cmake)" to get the path,
sudo doesn't seem to be available on the Travis CI windows
environment, so use $(which sudo) without quotes to expand to
nothing if that's the case...

This reverts commit 214aa0c1b0.

It was develop before, which is no longer used.

Actually, that function should be redesigned...

Considering chars inputs come in UTF8 form!
