I made a customawesome_title_tag view helper function because I wanted to support both controller views and live views.

Because of breaking changes between Phoenix 1.4 and 1.5, many examples out there did not work with Phoenix 1.5.
Here are some resources I referenced:
- Page title via live view route that’s compatible with existing code in regular views?
- @view_template meaning changed in phoenix 1.5
- Phoenix Live View 0.10.0 Backwards incompatible changes
That's it.
