routing: Add new roundup.web namespace with router component
This branch is to untangle hardcoded Roundup URL scheme, make
it more readable and customizable with extensions.
Right now it doesn't seem possible to write extension that
renders static HTML page at /about without modifying Roundup
DB, and this web component should not depend on DB schema.
