Create welcome layout

[zozobalogh0817]

The welcome layout should be driven from the default layout and has two options

• title (string) | This way user has control over the displayed title
• redirect (object { buttonText (string), redirectUri (string) } )| The user can tell where the user should continue and what text should sit on the button

On this page, all the content is centered.

The content structure will be the following

<h1>{{ title }}</h1>
	{{ content }} (content from the md file where welcome layout is applied)
	<button onclick="navigate -> redirect"><button>
