Improvements and fixes

A hidden inverter, combiner box or string now stays out of plant totals and reports.

• A hidden inverter, combiner box or string, and everything below it, drops out of plant totals, inverter power and reports.
• In an inverter's details, "Clear name" drops the name so it is picked up automatically again, which can take 30 minutes.
• How much of the daylight hours a device reported now counts only readings above 0 W; 0 W in daylight counts as not reporting.
• The components page now flags an inverter after 1 hour without data, and a combiner box or string after 25 hours instead of 2 days.
• Tables offer 10, 20, 50 or 100 rows per page, and the chosen size applies to every table.
