title: How to remove old repository URL from MercurialEclipse plugins repository location field
body: <p>I've a mercurial repository to which I push my changes with eclipses MercurialEclipse plugin, using Team -> Push. Now the repository URL has changed, and eclipse always remembers the old url in the input field, which is preselected as default, and I need to select the new one from the pull down list. Very small problem, but annoying none the less.. Is there a way to clear the old value from the field, so that I don't always need to pick the URL manually until the end of time?</p>
  
  <p>Alternatively, how to change the default repository entry to be the new one?</p>
