Make error module that takes an optional title and optional list of errors

[pastly]

And use it instead of aborting so much.

Can you please explain more of what you meant when you created this issue?

We abort(404) a lot, where 404 is some HTTP status code. This produces those ugly white error pages.

Instead of aborting, I suggest an error module, errors.py or an error page template. Spit balling ideas here:

• function that takes only an HTTP status code and returns a nicely styled page with the meaning of that code
• function that takes an optional code, optional title, and optional list of errors. It displays the title (if any) and errors (if any) and returns the page generated with the given code, or code 200 if no code

example pseudo code

def people.show(id):
    if not can_show(session, id):
        title = "Permission denied"
        errors = ["You do not have permission to see that person"]
        code = 403
        return redirect(url_for('error', title=title, errors=errors), code=code)

This example uses the template idea.
