Notification about new version in About dialog

[Olek Nowodziński]

Idea

Very often people don't realize that that our product is getting stable and richer. Users would benefit from updating CKEditor and, with a simple notification, we would let them know that "CKEditor lives".

The notification displayed in About dialog could look like that:

The newer version of CKEditor (<a>A.B.C</a>) is available (<a>Changelog</a>).

Technical background

When the About dialog is opened, a file is downloaded from ckeditor.com. It contains the latest version number and date, which is compared to the current version. If different, the dialog shows a message with a link to the download page.
