Paremeters:
- `pattern`: a string or regex to match in the outbound text. If
not provided or empty, the scriptlet will only log the outbound
text without modifying it.
- `replacement`: the replacement string for the matched part.
New special properties:
- `[-]`: remove an array entry if part right of `[-]` matches the
inspected item.
- `{-}`: remove a property if part right of `{-}` mmatches the
inspected item.
This is useful to remove entries which have unspecified names.
As suggested by https://github.com/distinctmondaylilac in internal

Usage:
...##+js(remove-cache-storage-item, cacheNamePattern[, urlPattern])
`cacheNamePattern`: the name of the cache to target. Plain string
or regex.
`urlPattern`: the URL of the resource to remove. Plain string
or regex. If no pattern is provided, the whole cache is removed.

Avoid race conditions between isolated world-side broadcast channel
and main-side broadcast channel, so as to not lose logging
information if the isolated world-side is not yet ready to
receive through its broadcast channel.
Additionally, added new scriptlet: `trusted-replace-argument`.
[...]##+js(trusted-replace-argument, fn, argpos, argval [,condition, pattern])
Where:
- `fn` is the function we want to proxy through an `apply` handler.
This can also be a class, in which case the scriptlet will proxy
through `construct` handler. At the moment, `fn` must exist at the
time the scriptlet executes.
- `argpos` is the 0-based position of the argument we want to change
- `argval` is the value we want to have for the argument -- the value
is interpreted the same way the value for `set-constant` is
interpreted.
- `condition, pattern` is a vararg which tells the scriptlet to act
only if `pattern` is found in the argument to overwrite.
Example of usage:
alliptvlinks.com##+js(trusted-replace-argument, MutationObserver, 0, noopFunc)
This commit brings the following changes to the logger:
All logging output generated by injected scriptlets are now sent to
the logger, the developer console will no longer be used to log
scriptlet logging information.
When the logger is not opened, the scriplets will not output any
logging information.
The goal with this new approach is to allow filter authors to
more easily assess the working of scriptlets without having to
go through scriptlet parameters to enable logging.
Consequently all the previous ways to tell scriptlets to log
information are now obsolete: if the logger is opened, the
scriptlets will log information to the logger.
Another benefit of this approach is that the dev tools do not
need to be open to obtain scriptlets logging information.
Accordingly, new filter expressions have been added to the logger:
"info" and "error". Selecting the "scriptlet" expression will also
keep the logging information from scriptlets.
A new button has been added to the logger (not yet i18n-ed): a
"volume" icon, which allows to enable verbose mode. When verbose
mode is enabled, the scriptlets may choose to output more
information regarding their inner working.
The entries in the logger will automatically expand on mouse hover.
This allows to scroll through entries which text does not fit into
a single row.
Clicking anywhere on an entry in the logger will open the detailed
view when applicable.
Generic information/errors will now be rendered regardless of which
tab is currently selected in the logger (similar to how tabless
entries are already being rendered).
