[development] HTML in node titles for D5

[Andrew Fountain]

There is an added complication with a link in a node in that when the node
is presented as a teaser, it will already be a link to the full node page.
Because of this we can only implement the hyperlinks when the browser is on
the full node page.

If we assume the simplest situation where the *whole node* is a link, I
would suggest using "[" and "]" as delimiters, something like this:
original node: *text of node [url]
*on node page after processing: *<a href="url">text of node </a>*
on teaser page after processing:* text of node*

In a more complex situation where you want arbitrary words in the node to be
hyperlinked, you can extend the sytax slightly with something like:
original node: *This is my node [with linked text:url] in it*
on node page after processing: *This is my node <a href="url">with linked
text</a> in it* on teaser page after processing: *This is my node with
linked text in it*

I haven't yet written the specific regular expressions you would need for
the above syntax. Sometimes it is best to adjust the sytax to make it easy
to write the regex.
