The filter option `empty` is converted to `redirect=empty`
by uBO internally; however unlike when the `redirect=`
option is used expressly, the `empty` option does not
require a resource type.
When `empty` is used, only network requests which are meant
to return a text response will be redirected to an empty
response body by uBO -- so `empty` will not work for
resources such as images, media, or other binary resources.

The color value for the icon badge is now
"attached" to the blocking profile value.
Additionally, as per feedback, `3p` rules
will be relaxing before master JavaScript
switch rules.

Additionally, the `3p` rule has been made distinct from
`3p-script`/`3p-frame` for the purpose of
"Relax blocking mode" command.
The badge color will hint at the current blocking mode.
There are four colors for the four following blocking
modes:
- JavaScript wholly disabled
- All 3rd parties blocked
- 3rd-party scripts and frames blocked
- None of the above
The default badge color will be used when JavaScript is not
wholly disabled and when there are no rules for `3p`,
`3p-script` or `3p-frame`.
A new advanced setting has been added to let the user choose
the badge colors for the various blocking modes,
`blockingProfileColors`. The value *must* be a sequence of
4 valid CSS color values that match 6 hexadecimal digits
prefixed with`#` -- anything else will be ignored.
The ability to redirect xmlhttprequest to binary
resources was lost when redirectable/injectable
resources became immutable in commit
152cea2dfe.
This commit restores the ability to redirect a
xmlhttprequest to a binary resource by making
it possible to derive a data: URI from the
content of binary resources such as images.
Addtionally a redirect to a data: URI can be
forced by prefixing the resource token with `%`.
This is a non-official feature at this point,
i.e. it could be removed at any time.

The purpose of this new option is to add the ability
to create standalone redirect rule without being forced
to create a block filter (a corresponding block filter
is always created when using the `redirect=`).
Additionally:
The syntax `*$redirect=token,...` is now supported, there
is no need to "trick" the filter parser with
`*/*$redirect=token,...` in order to create redirect rules
which are meant to match all paths.
Filters of the form `|http*://` will be normalized into
two corresponding filters `|https://` and `|http://` so as
to reduce the number of filters in the buckets of
untokenizable filters.

The following advanced setting has been added:
updateAssetBypassBrowserCache
Default to `false`. If set to `true`, uBO will ensure the
browser cache is bypassed when fetching a remote resource.
This is for the convenience of filter list maintainers who
may want to test the latest version of their lists when
fetched from their remote location.

Regression from converting uBO resources into
immutable resources. This affects only Chromium-based
browsers.
This is a quick fix for the dev build, to at least unbreak
the reported case.
I need to research whether the root issue (conflict with HTTPS-E)
is still occurring, and if so the fix is not trivial: I will need
to add code to uBO to fetch and convert binary data into `data:`
URIs.
Related Chromium issue:
- https://bugs.chromium.org/p/chromium/issues/detail?id=985759
By expressly restricting JavaScript execution to only code
from the extension package, this explicitly tells code reviewer
that uBO can't execute remote code.
I also had to add `object-src 'self'`, otherwise Chromium
refused to load the extension with the following error message:
> 'content_security_policy': CSP directive 'object-src' must be specified
`object-src 'self'` is the default value.
