Add docs custom send button label & icon optional keyword args

[plocket]

Closes #903, let author customize send button label and icon with keyword arguments. Added:

• keyword args
• types
• docstrings
• to download_list_html()
• to send_email_table_row()
• to send_button_html()
• to the test file

send_button_html() already had these options as label and icon.

A couple issues with the tests:

• ALKiln can't set up the test because it keeps getting a 504. Not sure what's going on, but no time to look into it at the moment. [I did test this manually.]
• I don't see a pull request from black-formatting

Black doesn't do a PR anymore. You need to do on command line.

I'll ignore the kiln failure , but let's get this migrated to GitHub only testing!

Shall I just look up a run-of-the-mill tutorial on black, or are we doing anything special?

Just pip install black, then black .

It's docsig main that seems to be failing at the moment [with "unknown option to disable 'E113'"]. If I have time today, I'll look into that.

We'll fix this in a separate PR. it looks like Docsig no longer supports the option to ignore error E113 (missing docstring).
