Deprecated Atom APIs will be removed June 1st

[benogle]

Atom will no longer load this package after June 1st without changes. There are a couple deprecations on the latest version (0.5.1) of this package:

1. atom.workspaceView is no longer available. In most cases you will not need the view. See the Workspace docs for alternatives: https://atom.io/docs/api/latest/Workspace. If you do need the view, please use atom.views.getView(atom.workspace), which returns an HTMLElement.
2. Call Workspace::addOpener instead
3. Requiring $ from atom is no longer supported. If you are using space-pen, please require $ from atom-space-pen-views. Otherwise require jquery instead: {$} = require 'atom-space-pen-views' or $ = require 'jquery' Add "atom-space-pen-views": "^2.0.3" to your package dependencies. Or add "jquery": "^2" to your package dependencies.
4. Requiring $$ from atom is no longer supported. Please require atom-space-pen-views instead: {$$} = require 'atom-space-pen-views' Add "atom-space-pen-views": "^2.0.3" to your package dependencies.
5. Requiring ScrollView from atom is no longer supported. Please require ScrollView from atom-space-pen-view instead: {ScrollView} = require 'atom-space-pen-views' Note that the API has changed slightly! Please read the docs at https://github.com/atom/atom-space-pen-views Add "atom-space-pen-views": "^2.0.3" to your package dependencies.
6. Store package style sheets in the styles/ directory instead of stylesheets/ in the <pack-name> package
7. Call ::getActiveTextEditor instead
8. If you would like your pane item with class <ClassName> to support modified behavior, please implement a ::onDidChangeModified() method. If not, ignore this message. ::on methods for items are no longer supported.
9. If you would like your pane item with class <ClassName> to support title change behavior, please implement a ::onDidChangeTitle() method. ::on methods for items are no longer supported. If not, ignore this message.
10. Pane item with class <ClassName> should implement ::getURI instead of ::getUri.
11. Use Workspace::getTextEditors instead
