Make seleniumbase become the only top-level Python package

[mdmintz]

Make seleniumbase become the only top-level Python package by making all other packages part of the seleniumbase package.

This means:

• "selenium_grid" moves to seleniumbase/utilities
• "selenium_ide" moves to seleniumbase/utilities
• "console_scripts" moves to seleniumbase/console_scripts
• "drivers" moves to seleniumbase/drivers
