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.
I'll make that happen in a separate diff.
