Speedup battery state update by only updating the battery list when we
get a CREATE/DELETE event in the directory or whenever we do a full
refresh on the interval.
full-at was capped at the value instead of allowing the battery to show
100% when you were at the full-at value. Uncapping makes more sense as
it makes the full-at value the new 100% and the scale goes down from
there. Whereas before the battery would stay at the full-at value until
it went down enough which is unrealistic.
Since we're now clamping at 100% and rounding, mark as full at that
point. Some batteries will stay in charging state for a long time while
stuck at the same charge level. Just mark them as full to not be
confusing.
The energy values are all that's needed to calculate the battery state.
Using other values for the total capacity results in broken results in
some cases. This matches the output of TLP and i3status, while also
being more straightforward.
In sway/workspaces, just like disable-scroll turns on/off the ability to
change workspaces by scrolling the mouse add disable-click that turns
on/off the ability to change workspaces by clicking.
