Update: start enum's at 1 where possible

By always setting enums as 1, the 0 value can be reserved as not-set.
There are still a few situations where enums must not start at 1.
Some are:
1) Type defenitions, so as in f_types where the status codes need to start at 0 for f_false.
2) Any enums that map 1to1 to an array, such as with parameter options.
