Non-technical users may not realize why they can not edit some events
from read-only subscribed remote calendars.
A symbolic padlock icon does not suffice to make this obvious.
This tooltip makes the UI self-documenting, and improves accessibility.
A more realistic default delay avoids spamming the search backends.
Benefits of this approach:
* Improves overall performance, allows wider search timeline ranges;
* Reduces power consumption;
* Reduces or eliminates flickering in the GUI;
* Reduces the amount of trace logging noise by more than 15x.

In commit 1494f7407, we focus the summary entry when opening the dialog.
However, this prevents the Escape keyboard shortcut from working
when opening a read-only event after having opened a writable event.
Set focus onto the "Done" button when showing a read-only event,
as it's the only widget that can be activated/clicked in this situation.
This makes the "Escape", "Spacebar" and "Enter" keyboard shortcuts work.

The "Done" button was apparently meant for read-only events,
while the "Save" action was for everything else.
It didn't work correctly because of a mismatch between code and UI XML.

Rewrite the text to properly market the app,
while avoiding referencing the target environment (GNOME).
Broadly emphasize the UX, existing key features, intended use,
and benefits of the application for the user in their day-to-day lives,
without over-selling it either.
We can augment this description in the future when more core features land.
Fixes issue #1109
These are still hardcoded instead of measuring the available space,
but it's better than nothing in the meantime.
Decent WMs size the window correctly if width/height exceed the screen.
Also, allow the Notes field to expand vertically, to fill the space.
