Register a custom scalar type for use in variable declarations.

Graphlient::Query::Serializer.scalar(:date, 'Date')

Typically called via the client configuration block:

client = Graphlient::Client.new(url) do |c|
c.scalar :date,    'Date'
c.scalar :uuid,    'UUID'
c.scalar :decimal, 'Decimal'
end

After registration, use the symbol in variable declarations:

query(created_after: :date) { ... }  # -> query($createdAfter: Date)
