Remove the HipChat integration

Goodbye, HipChat!
Atlassian has announced the end of HipChat in a deal with Slack. In response, I'm removing the HipChat integration in SeleniumBase, which posted test results in HipChat rooms after tests completed their runs.

Fix edge cases

• Don't let Firefox install updates in the middle of a test run
• Keep console logs under control when running Chrome on Windows
• Avoid multi-threaded test runs when using nosetests (Use pytest instead!)

Console script updates and driver updates

• You can now install web drivers by using seleniumbase console scripts:

seleniumbase install chromedriver
seleniumbase install geckodriver
seleniumbase install edgedriver

(SeleniumBase takes care of determining the latest version for your operating system's platform, downloading the zip file, extracting the driver from the zip file to the SeleniumBase drivers/ folder, and setting the permissions of the driver with "chmod" to make it executable for browser tests.)

• You can now run tests in headless mode without using pyvirtualdisplay.
  Usage: --headless. (Make sure you have the latest versions of Chrome and Firefox installed.)

pytest my_first_test.py --browser=chrome --headless

Fix the Docker integration

Console scripts update

Also updates Python requirements (six)

Small fixes

• Remove a debug statement from console_scripts that breaks Python 3.

• Have the Selenium Grid node connect to the specified Grid Hub server in Windows-based operating systems (localhost / 127.0.0.1 was hard-coded previously).

Add seleniumbase command-line interface for console scripts.

Add seleniumbase command-line interface for console scripts.

Usage:
seleniumbase [COMMAND] [PARAMETERS]

Examples:
seleniumbase mkdir [DIRECTORY_NAME]
seleniumbase convert [PYTHON_WEBDRIVER_UNITTEST_FILE].py
seleniumbase grid-hub start
seleniumbase grid-hub stop
seleniumbase grid-node start --hub=127.0.0.1
seleniumbase grid-node stop

Fix MySQL installation for Windows

Fix MySQL installation for windows. (Mainly removing the direct requirement because of issues installing mysqlclient directly, which mainly broke SeleniumBase completely when installing on Windows machines).
