Update 2019 Dev Meeting page with links to slides

[joelkevinjones]

Summary

I made two changes:

• For every presentation's slides that had been submitted but didn't have a link to them, I added a link
• For every presentation without submitted slides, I removed the anchor tag surrounding "Slides", so it didn't display as a link.

[joelkevinjones]

Ping. This change only adds links to files that are already uploaded, so I'm not sure what more I need to do.

Looks good. Thanks!
