which in many ways mocks java client's one

(i mean, there are probably lots of them, but this one triggered me for some reason)

because java client does it, thus we don't redownload already downloaded avatars
with spaces in names

this automatically 'caches' fetched rating history
for different leaderboards
because each tab has its own data and plot
and it's also more convenient than combo box

... and prettify their display names

see FAForever/Neroxis-Map-Generator#396
and FAForever/Neroxis-Map-Generator#401

map generator exits with 0 on wrong command line options
so the only way to check if error happened is to read from stderr
but the library, which map generator uses, also prints
the output of --help command after the error message
Starting from this commit we don't act upon second message
only log it just in case something else happened

to eliminite some duplicate code
also, add missed --num-teams argument

we are unable to predefine number of steps it will take
to generate a map
and seeing progress stuck at on of the first steps
when all the work is done in it is somewhat annoying

(using --debug option to display more information about progress
significantly (2x) slows down generation process, so we won't
use that)

(or at least try to do so)

some avatars' urls return 404

which is used since 1dd7441
but wasn't added to dependencies

as in java client, but these work

ugly fix, but fast and it works

it allows to use context menus and look at users' info
through replays
it also gives more control on how things are displayed
and removes html formatters

also, add display rating changes alongside the scores

and move all the "mean - 3 * devaition" calculations into 1 place

this fixes circular dependency me -> relations -> me

although it sound logical that User has relations
there is only one user, whose relations are known
and managable -- the client user (me)
so it is also logical for User class to not have
those relations
and maybe UserRelations should be the class, from
which we should get 'me', not the other way around

1. there are multiple leaderboards and their count can change
2. its behaviour is very inconvenient

it only needs avatar downloader

(special icon and no league name)

do not 'pre-parse' API response -- extract data
directly from the dictionary json.load provided
rating history responses can be very large --
tens of thousands of records, and skipping
default API response parsing and convertion parsed
data into pydantic models (especially skipping
pydantic) saves lots of time
additionally, using numpy arrays over python lists
and deleting unused data structures saves memory

don't create overhead signals and inherit LineSeriesParser
directly from QThread

it requires additional libraries to be installed
to work properly

so black numbers are visible on it

since a7197c7 view_replays uses
only player's login to search

which allows to disable ingame notification for everything except
the GAME_FULL notification
* apply common enabling/disabling rules to party invite notification
* fix NEW_GAME notification

the .msi file is stored in the 'dist' directory

the ImageDownloader's get_image method accepts url
