Add an 'Apply' button to the load template dialog

[Elliott Wave]

This is a small simple request to add an apply button to the load template dialog, that way different templates can be 'tested' without having to open the dialog every time.

At this point I have so many chart templates I can't remember what half of them are, and this would save a lot of time going through them.

Thanks for the suggestion. We will add it to the list of future considerations.
