Always show scroll bars

[bonzai]

Currently, the vertical scroll bar is only shown when needed, so sometimes the page is "jumping":

After this PR, the scroll bars will always be visible.

overflow: scroll never looks good on Windows

@zaknesler Nothing wrong with your screenshot.

@bonzai An empty scrollbar isn't a common choice of any website, it should only appear when necessary. The "jumping" is expected when switching to a page with longer content.

@bonzai The page is has more content that's why the Profile settings page has scrollbars, the Dashboard page on the other hand it doesn't so is has no scrollbars.
You don't need to show scrollbars on every page its not attractive to have disable scrollbars or even have scrollbars on a page that never scrolls, the users might be confused sometimes

[bonzai]

@zaknesler Well, I would expect that the menu or other elements of the page are always in the same place, no matter if the scroll bar is visible or not.
