Specify run options in Readme

[seaman1]

From documentation it's unclear how build/run Tests.
Since this basic framework have possibility to pass variables value through command line and through different profiles in pom.xml it would be nice to have examples how to do that. To be more specific:

1. how to build/run test and pass browser.name through command line.
2. how to build/run test using not active profile (for example: dev).
