installer: Rewrite welcome page.
The welcome page is the only page using absolute positioning for the newt components, so that the page occupies all the screen space. This is becoming too hard to manage, so switch to grid management like elsewhere, even if the result is less appealing. Also add an info text to the page with a mention on how to switch back to the original installer. * gnu/installer/newt/welcome.scm (run-menu-page): Use a vertically stacked grid instead of hard window placement.
