Deprecated Atom APIs will be removed June 1st

Atom will no longer load this package after June 1st without changes. There are a couple deprecations on the latest version (`0.0.1`) of this package:
1. Store package style sheets in the `styles/` directory instead of `stylesheets/` in the `` package
2. The context menu CSON format has changed. Please see https://atom.io/docs/api/latest/ContextMenuManager#context-menu-cson-format for more info.
3. Use `activationCommands` instead of `activationEvents` in your package.json Commands should be grouped by selector as follows: `json "activationCommands": { "atom-workspace": ["foo:bar", "foo:baz"], "atom-text-editor": ["foo:quux"] }`
4. 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.
5. Requiring `View` from `atom` is no longer supported. Please require `atom-space-pen-views` instead: `{View} = require 'atom-space-pen-views'` Add `"atom-space-pen-views": "^2.0.3"` to your package dependencies.

Visit https://gist.github.com/benogle/6d09e295c84b717ef9b4 and search for your package name to see up-to-date deprecations.

If this package has been replaced by another package or functionality in core, please reply with this information.

See https://github.com/atom/atom/issues/6867 for more info. Thanks!

Start with package.json and search the package source for stylesheets/, activationEvents, atom.workspaceView, and imports of View. Compare each occurrence with the linked Atom deprecation guidance; done means the listed deprecated APIs and directory or dependency conventions are updated so the package loads after the deadline.
