Release v0.15.0

• Fixed: a data point no longer holds a value of the wrong kind — a reading that stops matching the data point's type is discarded with one warning instead of being written into it
• Fixed: a NUT server that is switched off or restarting no longer makes the instance look broken — the adapter names the server it cannot reach and keeps retrying
• Fixed: value limits taken from the UPS disappear again when the UPS stops reporting them, instead of standing forever and causing warnings about every value outside them
• Fixed: credentials containing a space are now refused with an explanation instead of a bare protocol error nobody can act on
• Fixed: enabling instant commands now says why no command buttons appear when the UPS does not answer the command list
• Fixed: a UPS variable without a dot in its name is now writable, and can no longer take over one of the adapter's own channels
• Fixed: over a third of the data points carried an English label in every language — 157 more variable names are now translated into all eleven
• Fixed: the phases of a three-phase UPS, the sensors of a multi-sensor probe and the individual outlets no longer all share one name — each keeps the marker that says which one it is
• Fixed: the outlet buttons of a PDU are now named and explained like every other command instead of showing their raw NUT name
• New: explanations for the battery voltage, battery temperature, battery health and input current, which stood without one next to explained siblings
