Vscode: Feature Request: Hide workbench view via keyboard shortcut

• VSCode Version: 1.2.1
• OS Version: OS X El Capital

Steps to Reproduce:

1. CMD + SHIFT + E - Shows Explorer view
2. CMD + SHIFT + E - Pressing it again doesn't hide it

Same behavior for all workbench views.

I'd like to request the feature of hiding workbench views with either a unique shortcut or with the shortcut of the active view (making CMD + SHIFT + E a toggle Explorer rather than _show_ Explorer).

This behavior already exists with a mouse click (it toggles the workbench view visibility). Having keyboard shortcut support would be fantastic.

Thank you for the amazing editor.
