Title: issue 13 - Feature Request - enable yason:parse to parse JSON null as the keyword :NULL

Added variable `*parse-json-null-as-keyword*`.
Altered functions `yason::parse-constant` and `yason:parse` to accommodate new variable.
Updated relevant portions of doc.xml to reflect changes.
Export `*parse-json-null-as-keyword*` and :NULL.

By adding a new variable `*parse-json-null-as-keyword*` and redefining `yason:parse` and `yason::parse-constant` we can parse "null" as :NULL.
