Give child themes the ability to override parent theme template files on a per-file basis

[dnusim]

Specifying a parent Theme in your Theme's style.css will make your Theme inherit all of the template files from that Theme — meaning that any template files in the child Theme's directory will be ignored.

It would have been great if a child Theme could have the ability to override the parent Theme's template files - only inheriting template files that don't exist within the child Theme's directory.

This change would make it easier to customize a theme while still being able to take advantage of updates to the parent Theme without losing your beloved custom hacks.

thee17 do you have a reason to close this as invalid?

Reopening the ticket unless a reason to close it is brought up.

I'd expect it to inherit all parent theme templates, And any template files in the child themes folder would also be present, with any templates there taking precedence of the parent theme.. (If that makes sense)
