added packages to support markdown

added dummy pages for about and contact.
updated tailwind.config.js to include config/*.json to scan for classes.
refactored system basics. Removed component-props, using generic LayoutComponentDefinition and LayoutContext. cleanup component-map. Updated renderer to be more failsafe.

new abstracted components:
 vt-mega-menu,
vt-sidemenu,
vt-banner with 3 variants,
vt-header,
vt-homebutton,
vt-cartbutton,
vt-accountbutton,
vt-linkbutton,
