* pressing return/enter doesn't deselect the entity anymore
* predefined ("static") field options are always listed in the combobox dropdown, even if taginfo doesn't include them (because of low usage)
* (raw) tag values can also be entered for localized strings
* static localized strings can be used before taginfo response is received (useful when taginfo is slow or unavailable)
* fixes some bugs which can be triggered when taginfo is slow
* fixes a bug where the autocomplete dropdown doesn't work properly when tags have "few" values
* multiCombo fields can be case-sensitive now
For example, when a feature tagged as `highway=primary` (line preset) and `man_made=bridge` (area preset) is mapped as an unclosed way, converting it to an area (by closing the way by connecting the endpoints) does not improve the situation, as then the other tag doesn't fit to the geometry anymore.

This was taking a lot of time at app startup.
Instad now we resolve and index only the include and exclude parts.
We can still determine the valid locationSets at runtime in `locationSetsAt()`
by checking the `_locationIncludedIn` and `_locationExcludedIn` caches.
This also upgrades the locationManger to an ES6 class.
This also includes some hacky code in nsi.js so that the NSI will continue to work.
The NSI matcher can build its own location index, but it doesn't need to do this.
We monkeypatch a few of the matcher collections to work with the new LocationManager.
* previously, this check was based on the "fraction" of the respective tag value, which excluded more values for common tag keys, but fewer for less common ones.
* this sets a limit of 100 uses for undocumented tags (key=value pairs)
* tags with a wiki page are always allowed
* this harmonizes the heuristic of which tags to show between preset fields and the raw tag editor (previously, there was an additional `count > 10` filter present in combo fields, which is now uncessary)

this makes sure that the map extent is known when deciding which background imagery to load (e.g. which are valid in the viewport or which is the "best" one)
