* De-servicify router (mostly) Still uses the redraw service, but it no longer has an intermediate service of its own. Also, did a *lot* of test deduplication in this. About 30-40% of the router service tests were already tested on the main router API instance itself. Bundle size decreased from 9560 to 9548 bytes min+gzip. * Merge `m.mount` + `m.redraw`, update router Simplifies the router and redraw mechanism, and makes it much easier to keep predictable. Bundle size down to 9433 bytes min+gzip, docs updated accordingly. * Make `mithril/render` just return the `m.render` function directly. * Deservicify `m.render`, revise `m.route` - You now have to use `mithril/render/render` directly if you want an implicit redraw function. (This will likely be going away in v3.) - Revise `m.route` to only `key` components * Add `redraw` to `m.render`, deservicify requests * Test error logging * Update docs + changelog [skip ci]
