Unescape and use the filename when we have no title to display for a given entry (instead of displaying the whole path). This unifies the display of titles for local and remote files.

For anyone watching, this is how tab titles will change:
'http://blah.com/index.html' will be 'index.html'
'http://blah.com/meat%20pie.pdf' will be 'meat pie.pdf'
'file://C:/blah/blue%20cheese.txt' will be 'blue cheese.txt' (previously this sometimes changed between the URL and blue%20cheese.txt depending on how the file was opened).

The current implementation mimics Safari. I think it might be confusing to the
user if we just display the file component of an HTTP URL in case of a missing
title. For e.g. gallup.com would show up as index.aspx.

Would it be possible to display the filename for file based schemes?

I think showing the full URL for non-HTML remote resources is wrong (that is, if
you're looking at a PDF or image, you should be shown the filename). I guess
what we want is:
* URL for remote HTML content.
* Filename for all local content, and all non-HTML remote content (e.g. PDF /
TXT / Image).

Will investigate.
