Update `text` functions to `html` to support inserting the `span` elements
Specify `html: false` for various instances where a `span` is not desired, e.g. `placeholder` and `title` attributes
Consolidate localization behavior and init to a coreLocalizer function and singleton
Explicitly support `en-US` locale
Rename coreData to coreFileFetcher and export a singleton rather than using a property of coreContext
Add `apiConnections` property of coreContext to simplify adding a source switcher
Replace some init functions with re-callable, promise-supporting `ensureLoaded` functions
Make coreContext itself load the UI if a container has been specified at init time
Fix code tests
Add `utilCombinedTags` method and use it for the raw tag editor as well as fields
Pass `entityIDs` array into fields instead of single `entity` object
Give field revertion its own path separate from `change`
Add multiselection editing to fields in files: access, address, check, combo, cycleway, input, maxspeed, textarea, and wikidata
This better describes what it does.
Also, took this opportunity to update a bunch of the uifield code
(no multi line variable declarations, prefix state variables with _,
eliminate unnecessray lodash, etc)
(closes#4970)
They are still supported as translated strings, and user can still enter these
values in the raw tag editor, but they should not toggle with clicks in the
checkbox field. This is because novice users are confused by what they mean.
Fixes issue with nested/namespaced fields, such as `maxspeed/advisory`,
in situations where would try to use a css selector or element id.
Can't use characters like '/' in a css selector.
* convert iD.Detect() iife to a module
* iD.Detect() should return loaded locale (except for 'en')
(The previous code was a hack to replace the detected locale with the loaded
locale. Now that Detect is a module, we can not replace the detected locale
from external code, but we can have Detect() return the locale we really want)
