Add `try/catch` to `read` helper

Add a try/catch to the read helper. Previously, if a component template tried to read an asset that did not exist, the entire page would fail. Now, a log is sent to clay-log but the page will render as expected.

moving date-fns to be a dependency (rather than dev-dependency) to fix compatibility issues with other modules such as amphora-html

Upgrading handlebars

This upgrades handlebars. For some reason, v4.3 of handlebars is special. When the backend (amphora) uses a version > 4.3 and the frontend (kiln) uses a version < 4.3, it goes crazy. This breaking change is to hopefully normalize handlebars at v4.7.6 across all dependencies.

NOTE This was constructed off of v3.3.1 and not off of v4.0.0, so when upgrading from 4.0.0, we might need to do additional testing.

Dependency bump

Bump dependencies for security fix.

Security Patch

v3.2.6

3.2.6

sustainable-sourcing

• prevent handlebars-template-loader from trying to apply magic to <img src="">

NaNny-State

• instead of erroring, pass NaN as a string from num #49 (thanks, @byronhulcher!)
• instead of erroring, return falsy for undefined / null includes

inclusivity

• BREAKING - includes helper will not throw errors anymore when passed null/undefined/other falsy values. This allows you to use includes against more kinds of user-generated data safely.

clayreadme

• update readme to reflect new name

clayhandlebars

• renames nymag-handlebars to clayhandlebars
• migrates repo from nymag/nymag-handlebars to clay/handlebars
