Selenium project update
- using separate folder for config files
- new libraries + updates to existing ones
- page base practically unnecessary (methods moved to library)

Runner enhanced, new stuff:
- supports BS combinations to be passed through env variable or *.properties files
- supports option to run smoke tests only
- archives test results in zip folder
Checking for available BS sessions added
- waits for 1 hour, then terminates test execution if still none available
Small refactoring and styling changes
- added better comments to code
- removed some obsolete variables from config properties files
- other small fixes
