open-files package

This package adds an 'open files' pane above Atom's tree-view, mimicking the functionality of Sublime Text.

This package is basically a fork of the tree-view-open-files by postcasio, so most of the credit should go to him. The fork ports the package from coffeescript to ES6, and makes a number of modifications to make the 'open files' pane look similar to Sublime Text:

• The pane appears as part of the tree-view, sitting above it. It resizes automatically to show all open files, and it shares the same scroller as the tree-view.
• The 'open files' panel is collapseable when clicking on the label. An option in the settings tab makes it possible to make the panel uncollapseable.
• The 'open files' and 'folders' sections of the panel are clearly and elegantly labeled.
• The file list can be ordered alphabetically using multiple (cascading) criteria: filename (base), extension (ext) and directory (dir). The order of these criteria can be indicated as a (comma-separated) string in the settings. Default is: base, ext, dir. This is the same functionality that can be found in the tab-smart-sort package.
• The cross to close a file only appears when the mouse hovers over the entry (while the 'edited' marker is always visible).
• NEW in 0.6.0: In order to prevent the fast sliding down of the tree view when a file is added, there is a delay before the file appears in the 'open files' panel. The delay is configurable in the package's settings (default is 1000 ms, i.e., 1 second).
• NEW in 0.6.0: Files added and removed from the 'open files' panel are animated. The animation has a default duration of 300 ms, but this is configurable in the package's settings (default is 300 ms).
• NEW in 0.7.0: When several panels are open, the title for the 'open files' panels now includes PANEL #, with the number showing the order in which the panels were opened. When panels are closed, the numbers of the panels are re-calculated so that they reflect the panels present in the workspace
• NEW in 0.8.0: The icons mirror those of the tabs for all Atom views in both the file-icons and the seti-icons packages
• NEW in 0.8.0: The files in the 'open files' panel are automatically re-sorted when there is a file name change or a new file is saved for the first time. The icons also change automatically

TODO

• Make the files in the 'open files' panel draggable, and keep the tab order in sync with the 'open files' order.
• Configuration. Ideas and suggestions for further configuration options are welcome.
