I often need to quickly look at unformatted XML over and over and over again while
debugging. Today was one of those days and I got sick of it, so I wrote this.
It's simply an WebBrowser control on a form; when it gets focus it (optionally)
automatically displays the contents of the clipboard. The only options are
to automatically display the contents of the clipboard (otherwise you can CTRL+V
or Edit|Paste) and stay-on-top. I wrote this in a matter of minutes, so there's
no error handling or anything else.

Changes in v1.1:
A couple people actually downloaded and used this, so I made it a bit more friendly.
- Previously, if the clipboard was empty or had an empty string you'd be presented
with a "save as" dialog. I believe I've fixed this. (I can't repro anymore.)
- Temp files are now cleaned up.
