UA_List.inc.php now returns the array
Instead of setting a global variable $UA_List which is harder to work
with. Also modified the VendorsTest.php to use the return of the include
rather than the $UA_List global.
Added a test which is very similar to VendorsTest
This test, however, first converts the UA_Lists.inc.php to a
de-normalized JSON file and notifies you which tests were skipped due to
insufficient information in the user agent list. Also notifies how many
tests were run which is the same as how many user agents are tested.
