Pinboard.in 'Save a Bookmark' button

A very simple single purpose Pinboard ( http://pinboard.in ) extension: it adds an action button next to your address bar and when you click it the normal Pinboard "Save a Bookmark" page (as used in the bookmarklet) will appear in a popup with the current webpage URL and title pre-filled, as well as any text you may have selected for the description field. You can modify any fields, add tags and when saving the bookmark the popup will disappear automatically.

I wrote this small plugin since every other Pinboard extension at the time was trying to do more than just allow creating a new bookmark and I wanted to have as little clicks as possible.

Requires access to all pages in order to support the "use current selection as description" feature.

Full source code of this extension is available on my Github repository: https://github.com/aggregat4/chrome-extensions/tree/master/pinboard-save-bookmark

Changelog:
1.0.6 - Small typo caused a bug that prevented the popup from showing, should be fixed.
