the first-seen tier for which the machine was registered. So the
switching station, which is uniquely registered for all tiers, would
only visually connect to LV cable when placed, not to MV or HV cable.
(It would function nevertheless, and cable would connect to the switching
station if placed later.) Change to consider all tiers. Incidentally
avoid a gratuitous iteration through all registered machines.
When using the form to edit a chest label, apply the edited label whenever the
form is submitted with the text field included, rather than only if the form's
specific "finished editing" button is used. This supports the natural use of
<ret> to indicate that text editing is complete, which works with other text
editing forms such as that for signs.
Commit a6dae893d6 introduced per-version
charge cost for firing mining lasers, but applies this in addition to
the old fixed cost which it was meant to replace. Fix by removing the
application of the fixed cost.
The same commit did successfully change the check for a laser having
sufficient charge to fire, so that's based purely on the variable cost.
As a consequence, firing a laser that has just enough charge to cover the
variable cost could cause its charge to go negative. (For example, by
fully charging a Mk1 laser and then firing it until it empties, resulting
in a charge of -400.) It turned out that set_RE_wear handled that badly,
producing an over-100% wear value that would wrap to a *low* wear value,
leading to the laser's wear bar looking as if it's fully charged.
To protect against silly wear values, make set_RE_wear clamp the wear
value to avoid wrapping. Handle specially the case of a fully-discharged
tool, where there was desirable wrapping to zero.
