render template: show errors in output

[howardjohn]

Currently if a template has errors, they are silently ignored in the 'render template' command.

For example:

[9:14:21 PM] Rendering template:
result: {{ "bad" <  1}}

Result:

It would be nice if this instead showed

[9:14:21 PM] Rendering template:
result: {{ "bad" <  1}}

Error:
TypeError: '<' not supported between instances of 'str' and 'int'

how do I use this "render template" command? I'm not seeing it in the context menu?
