Performance-related work: the logger data has been decoupled
from the DOM -- inspired from CodeMirror's way of efficiently
handling large amout of text data.
This decoupling now makes the logger highly efficient CPU- and
memory-wise, and open the way to more possibilities.
Ability to configure some aspect of the logger behavior and
visuals:
- The hard-coded limit of 5000 entries has been
removed and is now replaced with a variety of
user-configurable settings to enforce the discarding of
logger entries.
- Some columns in the logger output can now be hidden.
The filter list look-up feature has been merged into the
existing overlay dialog used to create URL rules or static
filters, as an entry in a new "Details" pane.
Other issues addressed during refactoring:
- https://github.com/uBlockOrigin/uBlock-issues/issues/280

The minimum version supported on Firefox has been bumped
up to 55.0.

A new advanced settings has been added: `autoCommentFilterTemplate`.
Default value is `{{date}} {{origin}}`.
Placeholders are identified by `{{...}}`. There are currently
only three placeholders supported:
- `{{date}}`: will be replaced with current date
- `{{time}}`: will be replaced with current time
- `{{origin}}`: will be replaced with site information on which
the filter(s) was created
If no placeholder is found in `autoCommentFilterTemplate`, this
will disable auto-commenting. So one can use `-` to disable
auto-commenting.
Additionally, if auto-commenting is enabled, uBO will not emit a
comment if an emitted comment would be a duplicate of the last
one found in the user filter list.
I will need to fix the dev build script to ensure `updates.json`
file **on the master branch** is filled in with the latest dev
build details, regardless of the branch where it originates.
The DOM surveyor will now use time-based logic to spread its work
over time. This allows the surveying to better scale down on
slower devices.
Additionally, the DOM surveyor code has been reworked to lower as
much as possible memory churning when collating nodes to survey.
This rework has been motivated after profiling the "monstrous DOM"
seen in the following page:
<https://doc.rust-lang.org/std/iter/trait.Iterator.html>
The idea is that making the DOM surveyor efficient on such
"monstrous DOM" case should make it efficient everywhere in
practice.
