Merge branch 'beta' of https://github.com/z3t0/Arduino-IRremote into beta

Credits: https://github.com/LarsWH
Excerpt from PR:
```
Hi,

I added support for 'RC5 extended' in order to make this project:
https://www.instructables.com/id/Remote-Control-for-Lava-mMotion-Swing-Mounting-Bra/

The modification is working nicely in this single application. It has
not been tested elsewhere.

(I am new to Git and this is my first pull request ever. So please
excuse me if I have messed something up)

Kind regards,
Lars
```

 ## Usage
 - TODO (Check examples for now)
 
+## API documentation
+This project documents the library API using [Doxygen](http://www.doxygen.org).
+It is planned to make generated and up-to-date API documentation available online.
+
+To generate the API documentation,
+Doxygen, as well as [Graphviz](http://www.graphviz.org/) should be installed.
+(Note that on Windows, it may be necessary to add the Graphviz binary directory
+(something like `C:\Program Files\Graphviz2.38\bin`)
+to the `PATH` variable manually.)
+With Doxygen and Graphviz installed, issue the command
+`doxygen` from the command line in the main project directory, which will
+generate the API documentation in HTML format.
+The just generated `api-doc/index.html` can now be opened in a browser.
