- Added ability to send to Prowl via context menu! This will detect the type of item you're clicking on and react appropriately. Images get sent as their URLs, video and audio as their source URLs. Clicking on a page or in a frame will send the URL of that page. If you've got a selection of text on the page, that will get sent instead — useful for sending yourself a quick note!
- The context menu Prowl sending also works for actual tabs, as well as bookmarks, which can both save lots of effort if you want to send several.
- Updated the Add-on icon so it stands out a bit more and is easy to quickly find in the context menu.
- Updated the warning icon shown in notifications with a bit of color to quickly clue you in that something's gone wrong.

Fixed notifications not showing.
