Before this commit, the JS parser would add 0 after the input, then add the ean key.
Whereas reportlab.graphics.barcode fills the input with 0's on the left, then add the key

This commit makes the ean parser coherent with the lib the python uses
On firefox pressing special keys such as: Left Arrow or Backspace
trigger a keypress event.
This is different from google chrome which only generate a keydown and
keyup event.
There was thus two issue when using a FieldFloatScannable and firefox:
1. Keys such as ArrowLeft: would still be catched by FieldFloatScannable
and be added programatically to the field but since Odoo didn't fix
them a ASCII NUL character (0x0) would be added (in firefox it is
represented by a large space).
2. Keys such as Backspace: would still be catched by FieldFloatScannable
but were modified and corrected by Odoo so the corresponding ASCII
character was added (ASCII BS character (0x8) for backspace).
The feature in FieldFloatScannable which add the character is used to
add characters for which the browser had been prevented to display them.
Thus this fix:
- for issue 1 and 2: only use the feature of FieldFloatScannable if the
event was previously prevented and the current one is a forgery.
- for issue 2: add "Backspace" and "Delete" as specials characters which
should not be modified or stopped by the scanner heuristic.

Suppose the following usecase: you scan the first product of the
picking. A server onchange is then triggered. You scan the same product
a second time, before the first onchange has returned. You expect that
the first onchange is completely executed before running the second one.
This was not the case. Moreover, some onchanges were not be able to
work with the invalid state of the formview at some times, and crashed.
The previous implementation was wrong because id didn't run the main
barcode processing mechanism inside a Mutex. It was also wrong because
it didn't correctly wait for the onchange to execute (a previous barcode
onchanges or some classic ones) before setting the barcode field.
Using the constructor `new Event()` is not supported in IE >= 9.0
(tested on IE 11). It raises the below error:
`Object doesn't support this action`
This revision implements the Polyfill `CustomEvent()` suggested
by the MDN here:
https://developer.mozilla.org/en-US/docs/Web/API/CustomEvent/CustomEvent
and uses it if the `new Event()` call fails.

When we are trying to set the quantity on a mobile device, we get
a traceback saying that we cannot call the 'find' function on the
elements returned by '_get_records'.
This '_get_records' function returns a 'Collection' when called on a tree
view and an 'Array' when called on a kanban view. When we are working
on a mobile device, most of the one2many are displayed as kanban.
The thing is when we work with the object returned by '_get_records' we
call a 'find' method on it, which is implemented by Odoo's Collection class.
So when we call 'find' on an 'Array' we actually call 'Array.prototype.find' which
is implemented on most desktop browser and on some mobile browser [1]. This is what
caused the traceback on Chrome in Android.
To fix this issue, we enforce '_get_records' to always return an 'Array' and we ensure
that, when working on this 'Array', we use '_.find'.

The quantity event handler is not correctly unbound when its action
is deleted, resulting in multiple window.prompt asking the quantity
of the products if you go mulitple times trough a view when a widget
implementing the barcode thing is used.
There seems to be a bug in the framework ("barcode_scanned" events
are registered the same way than the "keypress" one on core.bus
but they don't have suffer from the same issue).
