screen comparison for hubs

POM update to selenium 2.43.1 + dependencies (apache httpcomponents)
test for comaring screenshot for hubs menu
There is convention to name test function in following way:
HubsMenus_001_comapreScreenshotsForHubsMenu

It makes it easier for other people to read the logs and rerun tests.
We are running tests base on the group name but log file contains method name so it makes it a lot easier to put group name inside method name
