Merge pull request #127 from hurrymaplelad/editor-duplicate

Listen for duplicate on atom.workspace
Register tree-view:remove on atom.workspaceView

This supports using it even when the tree view does not have focus
which will instead delete the active path.
Check document.activeElement in hasFocus

This allows the focus check to be correct when the tree view has focus
but the window does not and a command is triggered from the context menu.
Prepare 0.91.0 release
:bulb: Add data attributes on directory and file views

It’ll allow for complex theming of the tree view items through CSS
attributes selectors and without relying on another package that’ll
have to poll for changes (see DanBrooker/file-icons package).
Adds specs testing data attributes on tree view items
:lipstick: Use atom project method to compute relative path
:lipstick: Remove obsolete requires
Merge pull request #130 from abe33/feature_data_attributes

Add data attributes on directory and file views
Prepare 0.92.0 release
Add cross-platform support to show-in-file-manager. The "Show in file manager" menu option should now open the preferred file manager on Windows and GNU/Linux (and probably *BSD) as well as Mac OS X.
Use process.platform instead of os.platform() to determine operating system.

Have operating system specific lables for the "Show in …" menu entry.
The generic "Show in File Manager" menu entry is used for GNU/Linux, Solaris, and *BSD;
for Windows and Mac OS X their respective file managers are called by name (Explorer and Finder).
Extract operating system specific choosing of a suitable file manager calling executable to a separate method, as suggested by @bradgearon .
Fix broken :not selector in menu; needs element specified to work (i.e., body:not(.platform-darwin):not(.platform-win32) )
Fix inconsistent indenting warning by coffeelint.
