A new context menu entry, "Block element in frame...", will
be present when right-clicking on a frame element. When
this entry is clicked, uBO's element picker will be
launched from within the embedded frame and function the
same way as when launched from within the page.
This is particularly helpful for static network filters
used with filter options causing the same pattern to be
reused across multiple filter instances, i.e. `all` or
`~css`, etc.

When compiled data format changes, do not rely on order
of operations at launch to assume deletion of storage
occurs before attempts to access it. It's unclear this
commit will fix the reported issue, as I could not
reproduce it except when outright commenting out the code
to prevent the storage deletion from occurring.
The condition has been spotted occurring when bringing
up the DOM inspector for a page on which cosmetic filters
are being applied.
Not clear why this happens, but uBO must be ready to
graciously handle such condition.
All matching `redirect-rule` directives will now be reported
in the logger, instead of just the effective one.
The highest-ranked redirect directive will be the one
effectively used for redirection. This way filter list
authors can see whether a lower priority redirect is
being overriden by a higher priority one.
The default priority has been changed to 10, so as to allow
more leeway to create lower ranked redirect directives.
Additonally, rendering of redirect directives with explicit
priority has been fixed in the logger, they will no longer
be rendered as unknown redirect tokens.
The header value is no longer implicitly a regex-based literal, but
a plain string against which the header name is compared. The value can
be set to a regex literal by bracing the header value with the usual
forward slashes, `/.../`.
Examples:
*$1p,strict3p,script,header=via:1.1 google
*$1p,strict3p,script,header=via:/1\.1\s+google/
The first form will cause a strict comparison with the value of the header
named `via` against the string `1.1 google`.
The second form will cause a regex-based test with the value of the header
named `via` against the regex `/1\.1\s+google/`.
The header value can be prepended with `~` to reverse the comparison:
*$1p,strict3p,script,header=via:~1.1 google
The header value is optional and may be ommitted to test only for the
presence of a specific header:
*$1p,strict3p,script,header=via

Changes:
Negation character is `~` (instead of `!`).
Drop special anchor character `|` -- leading `|`
will be supported until no such filter is present
in uBO's own filter lists. For example, instance
of `queryprune=|ad` will have to be replaced with
`queryprune=/^ad/` (or `queryprune=ad` if the name
of the parameter to remove is exactly `ad`).
Align semantic with that of AdGuard's `removeparam=`,
except that specifying multiple `|`-separated names
is not supported.
`match-case`
------------

The new filter option `match-case` can be used only for
regex-based filters. Using `match-case` with any other
sort of filters will cause uBO to discard the filter.
`redirect=`
-----------
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/1366
`redirect=` filters with unresolvable resource token at
runtime will be discarded.
Additionally, the implicit priority is now set to 1
(was 0). The idea is to allow custom `redirect=` filters
to be used strictly as fallback `redirect=` filters in case
another `redirect=` filter is not picked up.
For example, one might create a `redirect=click2load.html:0`
filter, to be taken if and only if the blocked resource is
not already being redirected by another "official" filter
in one of the enabled filter lists.

Since the `redirect=` option was refactored into a modifier
filter, presence of a type (`script`, `xhr`, etc.) is no
longer a requirement.
