Extensions: create a simple model for the browser action buttons toolstrip and use it on Linux.

TODO: persist the order of buttons
TODO: use the model on windows, mac
TODO: let the view change the order of buttons

My plan for persisting the order is just to write/read a simple text file to/from disk, one extension id per line. Similar to the bookmark model, except that is structured data (because they try to hold more information).
