Add support for running multiple Chrome profiles sequentially

[znarfm]

This PR enhances the --profile argument to support running searches across multiple Chrome profiles sequentially.

Changes:

• Modified --profile argument to accept zero or more profile names
• Added profile-specific messaging in console output
• Updated README with the said changes

Example usage:

bing-rewards --profile Default 'Profile 1' 'Profile 2'

Cool! I don't use Chrome or multiple profiles, so I don't have an easy way to test this. But I will take a look and if it is working well for you, will probably merge.

Thanks! I use MS Edge and has 3 profiles on my browser, namely "Default", "Profile 1", and "Profile 2". I can say that it works well for me:

• was able to open the browser
• search something
• close the browser
• and do that for the next two profiles

However, I do not use Firefox and any Firefox-based browser so I did not test there. But AFAIK, the current code does not support the profile managing system that Firefox use, since the current code uses --profile-directory={profile} argument for opening the browser, which Firefox does not have.

Yes, I have never supported Firefox-based browsers, since at the time I could not find a way to launch the Firefox browser with a given user agent string using command line arguments.
