Embed quakenet's webchat
Since many webchat user disconnect rather quickly, replace the links to "https://webchat.quakenet.org/?channels=xonotic" with links to a new page on xonotic.org that embeds the webchat and shows the basic IRC rules.
Possible solution:
<embed src="https://webchat.quakenet.org/?channels=xonotic">
Maybe also a solution for #11 (closed)
