Move the sidebar to the opposite side when RTL

[Info 3bits]

Actually, when you change to a RTL language, Adaptable keep the sidebar in the same position. It should be moved to the oposite to keep the same layout.

Thanks for opening this issue.

It would be nice if:

• By default, the sidebar location would be set automatically based on the writing system of the language (RTL or LTR).
• However ,the Admin could enforce the location of the sidebar. That is for cases when users got so used to the sidebar being on the right side of the screen, that they wouldn't want its location to be changed, even in an RTL environment.
