We don't need to render all tables and use css to hide the ones we
don't currently want to see. Instead have `render` return the dom that
should be visible given the current state.
- Bumps the version of the extension to 1.0.1. We should bump the version immediately after every official release, so that any builds that happen after the release are treated as prerelease versions of the next release.
- Separates the components of the timestamp in the version number for non-release builds. This just makes it easier to read. I also left off the milliseconds, which were kind of overkill, and switched to using UTC time to avoid time-zone ambiguity.
- Updates the version number in the copy of the extension's `package.json` that winds up in the actual .vsix, so VS Code actually sees the version as being the proper prelease version.
