Allow the selection of a template from a list

[bitozoid]

This is an idea.

I would like to register in the options, a list of keys and templates that would be available for selection on every capture. That is, when I click capture, I am asked for the template to use from my predefined list.

This useful. The templates themselves should probably be defined in emacs but the extension could allow one to select from different template keywords (potentially allowing for different capture code as well).

PRs welcome!
