[Arte7Bridge] Support all languages

[tpikonen]

This PR adds support for all languages in arte.tv. I've used this for a while, and it works ok, at least for some value of 'works'.

Based on code by mitsukarenai from
https://gist.github.com/mitsukarenai/93c12e1470e2b731d64a31dffbe46075

This has never been tested with the web interface, I have generated local rss-files with commands like this:

/usr/bin/php index.php action=display bridge=Arte7 format=Mrss lang=en cat='' > arte_all.rss
/usr/bin/php index.php action=display bridge=Arte7 format=Mrss lang=en col=RC-020782 > making_history.rss

I basically don't know PHP at all, so I'm not going to maintain this code.

Also increases the limit to 100.

Fixes #1906.

Other than the limit, this looks fine.

This will break backwards compatibility, but I am a fan of making the bridge easier to maintain (no specific contexts for each language) and also adding basically 200% more languages.

I'll let @em92 decide because of seniority. But I think if we do this big cleanup, a few bridges backwards compat will be broken. And this bridge pr definitely comes with benefits.

Definitely not 100. Even 15 cover more than a month in all tested contexts (see bot commet). There is no reason to pull 100 items on every refresh.

Thanks, I changed the limit to 15.

We've broken multiple backwards compatibilities for the cleanup action, so I'm merging this.
