The link to rlgl in the README was broken, it previously pointed to a .c file which doesn't exist (anymore).

Fixes https://www.reddit.com/r/gamedev/comments/90z6fy/raylib_20_released/e2v5qpl/ :)

[ci skip]

cmake --build . --target package # or make package if make is used

can now be used to create binary packages for raylib.

AppVeyor and Travis CI are configured to push the artifacts
that result from building git tags to the related Github releases page.

We already have automatic Linux and macOS build via Travis CI.
This adds the same for Windows x86 and x86_64 with both
Microsoft Visual Studio 2015 as well as MinGW-w64.

Hopefully new videos comming soon...

Also adds commented-out deployment on tag specification
(push build artifacts to Github releases page).

Reviewed comments and added acknowledgements

Move raylib history to another file

Last character 'l' was missing on examples link.

Replaced LUA by Lua

Added some missing contributors...

Many thanks to Marcelo Paez (paezao)
