Get site options form to reload page on updating certain fields

[Robert Lyon]

When we update the language or theme fields it's not obvious that things have changed

We get a saved success message but things still look the same - we need to then refresh the page to see the changes.

This can be a bit confusing.

We had some code in the past to reload the page if certain field were filled in - by making the form submit in a non js way. But this got broken and trying to fix that breaks other things.

So instead I will get it working by applying the reload after the page save, with an 'Applying changes' popup to appear for a second before the page reloads

Bug 1854421: Allow site form to reload page on save

If certain fields are changed, like theme / language.
As we can't 'see' the changes until we reload the page.

We used to have some code to reload the page if theose fields changed
but it go broken over the years. This tries to fix that.
