Process JS API requests ($.request(handler, options)) through the document object instead of a non-existent form element. The form element was originally added because the framework only supported requests made from within a form
```
[22:08:12] spunky: The $triggerEl was implemented because previously it was just $form
[22:08:24] spunky: For data-requests without a form, these events were being ignored
[22:08:31] spunky: So as a workaround I implemented $triggerEl
```
As this is no longer the case, any JS API requests will now be made through the document element instead to support listening to events (such as ajaxSetup) even when there is no real attached element to trigger them on.
- Used for handling flash messages via JS API
Request options are now passed to ajaxBeforeSend & ajaxPromise events
Improved framework extras
- Fixes data-request-flash when used within a plain form, this code would fail because $triggerEl is set to a plain form:
`<form><button data-request="..." data-request-flash>...</button></form>`
Adds support for passing objects to be used as the loading indicator. Note: Objects must support `.show()` and `.hide()` methods.
Example:
```js
$.request('onHandler', {
loading: $.oc.stripeLoadIndicator
});
```
Notes:
Translations for all languages in preferences' drop-down should be written in native language not depending from current locale. As for example, you can take Youtube language settings at the bottom of the screen. And user can choose a language he can actually read.
As all localisation strings go to "en" as a fallback, we can just remove locale translations from all localization files except "en"".
This pipes all event calls through a new EventEmitter trait, which substitutes the October Rain event emitter trait. The view event has been moved to this trait also.
Pass some variables by reference to allow multi-extension.
Fixes#2420
