Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
The old behavior of restarting the timer after every second click could
result in double-click-chains (or triple+ clicks), which does not feel
like the right behavior.
By resetting the double-clicking timer, you need to perform a new full
double-click to make the arrows change color again.
Instead of using the doubleclick_event this uses the current double-
click speed setting to check whether or not the colors of the double-
click icon should be inverted. This allows us to use the current (and
unsaved) setting for comparison instead of having to apply the settings
first.
