VChat: Redone chat output done in Vue.js (#6761)

* Better notifications

* Add buttons to del/move tabs in edit mode

* Add a <span> to emotes

* Fix duplicate IDs in VChat and add more logging

* VChat: Redone chat output in Vue.js

* Ported tg asset cache

* VChat DME Update

* Replace \image macro with bicon()

* NanoUI Subsystem Fixes

Don't do this, the asset subsystem does this for you

* Allow narrate/globalnarrate shenanigans

Allows HTML if your entire thing is HTML

* Disable bicon() icon object cache, and create text tag cache

* Ore Scanner is written incorrectly

Only revealed by vchat

* Fixes 2 VChat bugs

* Underline links in VChat

* Fix LOOC color

* VChat Improvements

Hopefully, anyway.
- Arbitrary font size setting
- Line height setting
- Multiple crush settings
- Rewrote how tabs work hopefully for performance
- Hidden messages are actually put elsewhere
- Attempts to correct chat backlog restore on rejoin

* Surgery steps to use <span>

* Some VChat Tweaks

- Chat remains between client reconnects if your client didn't close (so things like using the reconnect button, or autoreconnects at round end when that feels like working)
- The client doesn't send pings to the server, the server sends pings to the client. This fixes AFK measurements for AFK kick purposes.
- Turn latency indicator into a green/red indicator to show if you're connected, and when clicked will perform a one-time ping (and block doing it again for 10 seconds). It will display '?ms' if it never got a reply, or '999ms' if it did, but it was over 1s.

* Include date in filename for VChat log save

* Merge pull request #6767 from Cyantime/patch-2

Change chat export naming scheme

* Adds VChat tab saving

Saves every time you enter/exit edit mode. Persists between rounds, VChat reloads via verb, etc.

* Fix chat exporting when someone has used unicode

Only affects clients still using 512

* Use CLIENT_FROM_VAR for ease of code reading

* Update code/modules/client/asset_cache.dm
