[Feature suggestion] Solution-wide and system-wide templates.

[HTD]

Just one little thing - system-wide or at least solution-winde templates.

I have a solution with over 20 projects, putting templates in every project would be tedious and would create a mess in the files.

It would be super cool if I could just put the templates in a default VS templates directory or a solution directory. The path to a template should be resolved from - project (top priority), solution (intermediate), system (when not found in previous folders), built-in (when not found anywhere).

Someone very recently sent a PR that supports this very thing inside solution .templates directories
