Fix #95, #384 - Use electron-context-menu, supporting cut/copy/paste (PR #588)

The electron-context-menu package uses the context-menu event emitted by WebContents (API added in Electron 1.0.2) to add a general context menu supporting generic actions (e.g. cut/copy/paste) that can be customized. This change replaces the existing context menu, which relies on adding an event listener in preload.js, with one built using the new package.
