Expose toggle for SchedulesDirect Image downloading and correct base URL

[carlreid]

Description

The settings toggles for ENABLE SERIES POSTER ART and ENABLE SERIES WIDE SCREEN ART were exposed on the UI, but all the back-end logic had been commented out. This change now re-enabled just the ENABLE SERIES POSTER ART option, as the ENABLE SERIES WIDE SCREEN ART can probably be controlled by SERIES POSTER ASPECT RATIO(?).

However, this setting was unused currently. So StreamMaster by default was attempting to download the poster/images. The problem was that the URL was not being built correctly, meaning that the content was not downloaded.

Issues (Fixed or Closed)

• Fixes Bug: Schedules Direct Poster Art settings NOT saved. #101

Type of Change

• Bug fix (non-breaking change which fixes an issue)

Testing Instructions

Toggle on ENABLE SERIES POSTER ART. Should now see program images appearing in EPG (might need to restart StreamMaster to force a sync) sourced from config/Cache/ProgramLogos
