logging tweaks - port from conjuro branch
Reverting previous limitation as we now fetch more results than the limit, https://github.com/midgetspy/Sick-Beard/commit/7919f05d5b1b5d9a889cf85cd482ac1984c55991
If there are more than 100 results for a query, fetch up to an additional 300 results (4 hits total). Mainly for when we search without tvrage id set.
Handle when newznab servers take their API offline more gracefully.
Add logic to fall back to query by string if tvrage search returns 0 results.
PEP8 fixes
Add zap2it to mede8er's metadata, only show id if populated.
Add xml declare when writing .xml files (apparently mede8er requires it..)

PEP8 fixes, remove some old debugging log messages and cleanup.
Only show format pattern debug info when called from config > post-processing for naming test, otherwise suppress.
  > This reduces three log messages for each instance, which can add up quickly: provider (+ generic) + metadata + notifier. So four instances for one ep manual search with one provider enabled... so 12 log messages that were not needed.
