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
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)
