[Windows/Linux] Command line interface + bug fixes

Hello, quick patch to fixes somes bugs and add the possibility to use command line interface to host and join a hosted game directly without having to go through the game interface !

Only available for Windows and linux, this update will come for Mac later.

Changelog 0.11.9b - 5 feb 2021

Changes:
- Now it's possible to use the command line interface to host a game directly. Ex:
./PlanetCentauri --host -p 7777 --user 0 --world 1
(for powershell :  replace / by \\ )
Note: it will not start an headless server, but this is planned.
- We can also use the CLI to join without the need to go through the main menu. Ex:
./PlanetCentauri --join --ip onidev.fr --port 7777 --user 1
- brutor transformation: running by default
- don't display the 'R' tooltip on mounts if transformed
- don't display blocks/deco previews if transformed

Fixed:
- if client transformed, new chunks are not loaded
- Monsters are invisible in magic preview / skill previews
- skeleton: if special spawn, become invisible after the animation
- scorpion and skeleton miniboss crash
- ice eagle: no name, no damages, no loots
- bullet/beam attack of multiple monsters do only 1 dmg
- block picker is now disabled if player is transformed
- block picker is now disabled if a chatbox is open, even if we don't write
