Improvements/bug fixes

• Fix widget display when running on OS 10.4.x - the widget should now load properly and not just continuously display the "Retrieving data…" text.
• Change cursor shape to resize cursor when mouse is over the resize corner.
• Correct minor visual glitch when first showing the Dashboard after login.

Complete re-write of the widget to properly work with the re-designed SigAlert website.
As the widget content is now being served directly from SigAlert instead of having the widget to manually parse all the data, the widget should be much more stable and automatically profit from updates to the website.

Improvements/bug fixes:

Fix "regular expression too large" error causing the widget to get stuck at reloading data for "My Sigalert" subscribers after upgrading Safari to version 3.1.
