update vdom to 0.0.21 to include recent fixes

[pfrazee]

I ran into some bugs that were fixed with this change: Matt-Esch/vdom@a6c1691#diff-f68b7b3bc64a462a8c2606af9a9d4178L47

yes, i think an update is in order - we should also update vtree due to a recent fix. however, updating vdom in mercury requires more than just updating mercury. main-loop also depends on vdom and vtree and virtual-hyperscript depends on vtree. those should be updated and published and then mercury can update, build dist, and publish.

• update vtree dep in virtual-hyperscript
• publish new virtual-hyperscript
• update vdom and vtree deps in main-loop
• publish new main-loop
• update main-loop, vtree, vdom, virtual-hyperscript, observ-struct, observ-array deps in mercury
• build new dist for mercury
• publish new mercury
• close update vdom dependency #82, update vdom and vtree deps #83

EDIT: i added updates for observ-struct and observ-array to the list as well since those have newer versions too.

I'll do an update of everything tonight.

Actually, I have things to do tonight -.- might not get around to it.

Expect it to be updated over the weekend.

Also note that the step @neonstalwart missed in his list is manually testing all the examples. Shouldn't be too bad though.

I updated vdom.
