/*
v0.53 - Apr 20, 08
* Fixed minification regexp (added a few characters)
v0.52 - Apr 2, 08
* Fixed some design issues - excluded/highlighted entries doesn't affect the content of the entry (thanks Paul Irish!)
v0.51 - Mar 31, 08
* Fixed minification regexp (old one omitted numbers)
v0.5 - Mar 30, 08
* Fixed some bugs
* Enhanced filter
* UTF-8 characters support
v0.4 - Mar 26, 08
* Added the ability to hide duplicates/excluded entries, new checkboxes added in settings window.
v0.3 - Mar 19, 08
* Duplicates also marked as excluded. Duplicate is an entry whose url or title were already printed.
v0.2 - Mar 16, 08
* Added "Quick Add" window, which lets you add new exclude/highlight to the list from within an entry ([#] button is added to each entry on its right)
* RegExps are compiled only at initialization and after saving, not like before
v0.1 - Mar 8, 08
* First Release
