The module `Data.Aeson.Parser` is moved into attoparsec-aeson for aeson >=2.2.
For aeson <2.2, attoparsec-aeson is an empty package, since the module exists within aeson.
Fixes https://github.com/yesodweb/yesod/issues/1771
This is done by adding a function to Yesod
typeclass which can match on any exception
and tell the framework if it should rethrow
or not.
I used an overridable function because it seemed
more flexible then a whitelist.
A user can now for example choose to throw
everything, or catch everything as easily.

Like setTitle, this function should really be idempotent so developers
don't add multiple conflicting meta descriptions to the page. Unlike
setTitle, the function currently fails its idempotency test.
* Add functions for setting description and OG meta
It's common that a website author will want to add a specific
description and Open Graph image to a given page in their website. These
functions are simple conveniences to add these meta tags to the document
head.
I decided against simply adding all possible meta tags, because not all
of them are useful, and even in the case of Open Graph tags, many of
them should be set only once and they should use the same value for the
entire website. In those cases, it's probably better for the website
author to add those tags in their layout template.

This adds `jsAttributesHandler` to run arbitrary Handler code before
building the attributes map for the script tag generated by `widgetFile`.
This is useful if you need to add a randomised nonce value to that tag.
