also, titles for opml export

[Bruce D'Arcus]

I figured out the HTML transformation for OPML, but discovered that 
when OO exports the title it includes the "ooutline" extension.  Please 
fix this.

If I title a document "The Title" and it gets an OPML extension, that 
later gets changed to HTML, I should just get "The Title" in the 
browser window, not "The Title.ooutline."  Moreover, I would tend to 
say that, if possible, the title ought to be the title of the OPML file 
I save to, rather than the original .ooutline file.
