Add SQLDriverConnect 'GUI'

When applications call `SQLDriverConnect` and ask us to prompt the user for more
information, we now pop open notepad as our GUI.

Renamed `schema` connection parameter to `prestoSchema` because Tableau assumes some
sort of undocumented purpose for `schema` and fails to retain it in the connection
string. This fixed a long-standing point of confusion.

Added an alias to the `database` connection parameter, `prestoCatalog`.

Added another markdown file to describe the connection parameters and how to enter
them.

Future work: In the future I shall try to present a more user-friendly template
in notepad. For now, this should actually enable MS Query to work, I shall test that
and revise the readme in a near-future diff.

You may note that process.d from Phobos was added in this diff. For more details about why, please see the comment I added at the top.
For both this comment and the next, the terminology is based off of what Tableau chose more than anything else. Since we are already (as of this diff) half way to saying "forget the Tableau UI", I am OK with just renaming everything.

How do you feel about `endpoint` as a name that combines host and port?
