improve directives

1. DEADEND defeats the collaborative purpose of the site, and BACKLINK
is fairly useless without it.
2. PAGETITLE has been added, and it should be useful in cases where
REDIRECT is used heavily.

-	type <code>#BACKLINK &lt;room&gt; &lt;action&gt;</code> on its own line to cause the room to link back to an already existing room. replace <code>&lt;action&gt;</code> with the text you desire to appear in the link. replace <code>&lt;room&gt;</code> with everything after <code>https://zzcxz.citrons.xyz/g/</code>. for example, to make a link with the text "go back" which links to <code>https://zzcxz.citrons.xyz/g/xxxxx</code>, type the line <code>#BACKLINK xxxxx go back</code>. <code>#BACKLINK</code> cannot add new actions.
+	type <code>#REDIRECT &lt;room&gt;</code> on its own line to cause the action to bring you to <code>&lt;room&gt;</code> instead of a new room. replace <code>&lt;room&gt;</code> with the five letters at the end of the url of the desired room. for instance, to make the action link to <code>https://zzcxz.citrons.xyz/g/zzcxz</code>, type <code>#REDIRECT zzcxz</code>.

-	type <code>#DEADEND</code> to prevent people from taking additional actions on the page. this is mostly useful in combination with <code>#BACKLINK</code>.

 	<li>
 	you can add <code>/raw</code> to the end of the URL of a room to see its markup (on the lines starting with tab) (<a href="/g/zzcxz/raw">example</a>). this feature could also potentially be utilized to implement third-party interfaces.
