Previous code was problematic because we need the function to
to properly blacklist custom imagery passed in through the url hash,
before iD is completely initialized. Triggering GET causes tests to
break because osm service testing has side effects :-/
* if 509 Bandwidth Exceeded / 429 Too Many Requests, prompt for login
(closes#2262)
* if 400 Bad Request / 401 Unauthorized / 403 Forbidden - logout and retry
(closes#3546)
(closes#3324)
Previously we allowed devs to swap out services that they didn't need.
This became difficult now that ES6 exports are immutable bindings.
But we can wrap the immutable bindings themselves in a live object,
to get back the flexibility that we used to have.
This change also drops the `taginfo` accessor on Context, since devs who want
to swap out taginfo service with something else can now do so through the live
binding. `iD.services.taginfo = myTaginfo()`
(closes#3377)
In most cases we prefer taginfo value results with lowercase letters.
A few OSM keys expect values to contain uppercase values
This is not an exhaustive list (e.g. `name` also has uppercase values)
but these are the fields where taginfo value lookup is most useful.
* 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)
