Title: [feature/editor-code-tabs] Allow tabs when typing code

Allow tabs when typing code in textarea.
Keep indentation when typing code in textarea.

It only works when user is typing inside [code] bbcode. If user is not typing code, behavior isn't changed.

Works with modern browsers and IE9+. Older browsers will see default behavior.
