[PATCH 2/2] toaster/tests: browser add class SeleniumTestCaseBase

["Aníbal Limón" <anibal.limon@linux.intel.com>]

Add a new module with base class SeleniumTestCaseBase only
with inherit of unittest.TestCase for reuse selenium helper
in functional testing of Toaster outside django environment.

Add class SeleniumTestCase with multiple inherit of
StaticLiveServerTestCase and SeleniumTestCaseBase for don't
broke things.
