PyAPI: remove support for importing text blocks as modules

Allowing direct import of text blocks isn't especially useful,
instead add `text.as_module()` script authors can do this
explicitly if it's needed.

Now the text "Register" option executes
instead of loading as a module.

This removes the need to keep track of the current Main,
and C code to override Python's import & reload.
