Provider getURL and downloadResult functions now removed and replaced with ones from helpers.py to help slim the code down plus allow more better control over request sessions. Removed TVTumbler code. Fixed HDBits provider. Fixed config settings that were ment to be booleans but instead where set as str or int, should help resolve random html errors. XEM Refresh check re-coded. NameParser code for creating show object has been changed to only attempt at the very end once its found the bestMatch result, helps on resources and performance.
