Subject: [PATCH] Add feature to open image attachments

Images that are attached to messages, either sent or received
can be opened in a new tab by clicking on them.

The previous approach that used Anchors to open the image
attachmets failed in various systems because:
 - Chrome on Windows recognised "blob" as protocol and tried
   to find an app for it
 - Chromium on Ubuntu didn't open a new window to load the URL

The new approach adds a "click" listener to the IMG element and
opens the link using window.open (which seems to be working globaly).

Resolves: #252
