George Cushen 8d75e9e27a feat: add options to highlight active links and show current language
`highlight_active_link` and `show_language` added to `main_menu` in `params.toml`:

`main_menu = {align = "l", show_logo = true, highlight_active_link = true, show_language = false}`

For example, enables disabling highlighting active main menu links on scroll if it's found to be inaccurate in a certain case, such as towards the end of a homepage with lots of very short widgets that are linked in the menu.
