Adding an example migration for richlistbox
== Removed in Thunderbird 63 ==
* XUL elements <tt>listbox</tt>, <tt>listboxitem</tt> and <tt>listcell</tt>. <br/>Replacement: <tt>richlistbox</tt>([https://github.com/jobisoft/CategoryManager/commit/2267888be7de0d7ebe4f5b4626c48210c071b16f example migration])
* XUL <tt>stringbundleset</tt> / <tt>stringbundle</tt>. You will also be unable to use the `nsIStringBundleService` interface.<br/>Replacement: Use <tt>Services.strings.createBundle(...)</tt>.<br/>In order to use stringbundles, you need to load stringbundle.js in your XUL: <tt><script type="application/x-javascript" src="chrome://global/content/elements/stringbundle.js"/></tt>, but the XUL Overlay loader takes care of this. See also [https://bugzil.la/1459743 bug 1459743]
* <tt>mailServices.js</tt> has been renamed to <tt>MailServices.jsm</tt>. The old name keeps working for now, but you get a deprecation warning in the error console if you use the old name.
