HSD8-1572: Add photo ID to local event image filename

[joegl]

READY FOR REVIEW

Summary

• Add photo ID to local event image filename
• This will create a new image if the event photo changes and prevent long-term caching when an event photo changes
• I also added a trim (substr) on the urlname to 220 characters just to ensure there's enough characters left in the filename for the photo_id and file extension.

Example filenames from my local:
