Rtl proposals
Recently the rtl and ltr icons need was discused on telegram.
A document was written by @Sithlord48
which I formated in this branch.
I also added some my opinions.
This topic has a difficult aproach because none of us are rtl language users so any intent hasn't any base.
The merge request should be aproved if the tables inside the rtl-proposals.md
file reflect what we are going to do.
