Updating Supported Files- Weekly Update

We added 2 small updates: 1. To make the extension work on all kinds of files (up until now, it supported only javascript files), we changed this line: to the following line: which means- support all kinds of languages. 2. We added a button 'Open In Browser' on the hover panel, which opens the image in the browser: The final details for the image part of the extension are: 1. Add another button -'Open In A New Tab'- which opens the image in the webview panel we already made. (check how to create a button on click event in markdown?) 2. Right now, the extension must be called for each image we want to preview. We don't want that, so we need to understand how to notify when the selection has changed, and change the image if needed. (while or an event? the activate function should never end?)
