Add ad-blocking functionality

Add ad-blocking functionality

Usage:

On the command line:
"pytest SOME_TEST.py --ad_block"
OR
"nosetests SOME_TEST.py --ad_block"

From inside a test:
self.ad_block()

Uses AD_BLOCK_LIST from seleniumbase/config/ad_block_list.py to determine what gets blocked.

Use Python standard library methods when possible

I'm replacing an old method I wrote a long time ago called jq_format() with a Python standard library method that I probably didn't know about then, called re.escape(), which performs the same intended action.

Minor updates

Don't set a specific version for pip & setuptools

Minor updates

• Use plain javascript instead of jQuery when highlighting elements because some websites (such as GitHub) have Content Security Policy directives that prevent loading jQuery for custom scripts.

• If waiting for angularjs to load as part of ready state, wait less time

• Set maximum time for activating jQuery to be settings.MINI_TIMEOUT

Adding more methods for handling webdriver actions

• self.open_new_window(switch_to=True)
• self.switch_to_window(window, timeout=settings.SMALL_TIMEOUT)
• self.switch_to_default_window()
• self.get_new_driver(browser=None, headless=None, servername=None, port=None, proxy=None, switch_to=True)
• self.switch_to_driver(driver)
• self.switch_to_default_driver()
