Feature Request: reload single file/app

[dlashua]

When developing a new pyscript (without Jupyter) it is often necessary to restart pyscript to load changes made to the new script. If one has many scripts with informational startup messages, parsing the logs becomes tedious. Having the ability to restart only ONE script would be useful in this scenario.

pyscript.reload could take an optional 'script' argument that should be populated with "file.test" or "app.test" to indicate what to reload.

Alternatives:

• User should make startup less verbose on other scripts.
• User should use Jupyter for script development.
