Share availabilities improvements

Cron’s Share availabilities is the best way to place some holds on your calendar and get a text snippet of those time windows. And it just got a lot better.

The visual overhaul makes the picked slots clearer and fun when “scratching” the slots open. In addition, the same powerful multi-select from events (hold ⌘ while clicking) also works for holds.

The right-hand context panel got more powerful: you can edited fields directly (without having to enter edit mode first), get the snippet in the clipboard automatically after clicking “Create”, and you can delete individual holds from the context panel.

Finally, we’ve dropped the /meet path for cleaner and shorter booking links.
