Added Hidden Folder check for Windows Attributes

- Changed helpers.is_hidden_folder to utilize Windows GetAttributesW DLL
function to get folder attributes.
- Changed call to is_hidden_folder to use the entire path for the call,
instead of just the foldername.

Fixes https://github.com/SiCKRAGETV/sickrage-issues/issues/554
