Add PermissiveBoolean datatype
Add PermissiveBoolean datatype

<xs:boolean> can either be 'true', 'false', '1' or 'O' ; but many
Galaxy tools use 'True' and 'False' (capitalized), which appears
to be ignored/accepted by Galaxy.
This PermissiveBoolean type is meant to be used in place of xs:boolean
when needed.
