Improve inline docs for register_post_type() and register_taxonomy(). 

* register_taxonomy: Use the same doc format for the associative array arg as used for register_post_type()
* register_taxonomy: Improve docs for _builtin, capabilities, hierarchical and rewrite args
* register_taxonomy: Use the same order in $defaults as in docblock
* register_taxonomy: Replace is_null with null ===, to be consistent
* register_post_type: Use the same order in $defaults as in docblock
* register_post_type: Improve docs for @uses and default fallbacks
And while we're on it: Whitespaces.
