Two proptypes missing

[garyee]

Hi,

frist of all: very nice extension!
refereing to this List
I have gathered all the PropTypes:

PropTypes.array,
PropTypes.bool,
PropTypes.func,
PropTypes.number,
PropTypes.object,
PropTypes.string,
PropTypes.node,
PropTypes.element,

PropTypes.symbol,
PropTypes.any

The last two are missing in then PropType-snippets. Did you forgot them or did you leave them out on purpose? If it is the former could you maybe add them?
