News Interceptor 3 Beta 18

We added a useful feature for those using Internet Explorer: opening news into a new browser window. To activate this feature, open the Preferences window, click on the News tab and check the "Open in new window (Internet Explorer)" option.

Here is the complete list of changes:

- add: new option to open news into a new window when using Internet Explorer (you must activate it in the Preferences);
- add: verification button to test connectivity with a private RSScache server;
- fix: HTML tags are displayed in news title;
- fix: erasing a news doesn't update the news pane.
