htools: improvements to JSON deserialisation

This fixes two problems:

- first, when we deserialise a big object, showing its value is not
useful, as it will hide the actual error message
- second, we shouldn't deserialise a container at once, because then
we will lose the detail of which 'key' failed to deserialise; we
change to manual deserialisation of each key/value pair, so that we
can keep this information

The last point requires that we import JSON.hs into THH.hs, in order
not to duplicate functionality.
