Feature #286: Allow slide to close on videos

[Beagon]

This should add the functionality proposed in #286

I've added a setting "touchVideoClosable" with default as false as to not interfere with legacy applications. The code itself has been added to touch-navigation.js.

I changed the name of mediaImage to mediaElement since it's not only about images anymore.

Of course also added the touchVideoClosable setting to README.md so the docs stay up to date!

@Beagon You still need to run the watch command, that will build everything into the dist folder. Other than that comment I made about the description on the README, everything looks good to me 😊

Hi @Frankie-tech,

I misread the CONTRIBUTING.md then. I saw the following line DO NOT commit changes in the dist directory, this files are created automatically. and didn't want to commit anything from dist :)

I've updated the PR.
