RNA & PyAPI

* support for dynamic enums to be inspected enumProp.items() from python.
* fix, enums check for a separator was flipped, meant no enums were in docs.
* dynamic enum functions now check for a NULL context and return all possible options for the "items" attribute used for docs.
* added an arg for rna arrays to free the array there looping over (needed to free dynamically allocated enum items)
* python api checks for NULL items since this can happen in some cases.
* python api, When getting an enum ID from an int in an array - If it failed it would get the first enum identifier and return that. Brecht? dont understand, making it return an empty string in these cases.
