[FEATURE] Silence notifications and more buttons

[laaledesiempre]

It would be awesome to add a Silence sounds button somewhere, also it would be great to add some buttons between memoChums and textarea for simple items like :HONK: and stuff.
Also would be great to add a button to show a modal with all pesterchum features as rol and emojis.

i didnt touched a lot of the js because it seems kinda "fragile". i'm not used to the stuff @Dpeta made (i know that only you work in this but if someone else read this wont know who is "you"). and maybe touching it for me is worst, but here is some info that may be usefull for you if you wanna to add some of this button features:

add all that buttons into a div, add to this div an identifier (class OR id, i dont need both if you want me to do the styles (i would be happpy to help!).) and then all the buttons inside, maybe with the icons taken from the smilies folder.

i think thats all. feel fre to close it and split it on multiple issues if you want! have a nice day!

All of these would be useful to have sure. A silence button especially is definitely needed, I always just mute the tab </3
