 At present, all taxonomy-related actions are based off the
 {{{manage_categories}}} capability.

 This means that plugins are not able to restrict who can modify/delete
 their taxonomies terms.

 In the same light, This also restricts site managers from only allowing
 certain users(roles) to handle specific functions.

 I'm commiting a first-scrape at it, Things that need to be looked into:
  * MultiSite integration
  * Tag-style taxonomy additions (ie. Allowed to manage(add to post object)
 but not add)
  * viewing of the post page should allow the user to see the current
 terms, but not change them (Current code will hide them entirely)
  * Ensure that when a user modifies an existing post, terms are not lost.

 The caps are currently changed by passing one of the following args to
 register_taxonomy, empty() or not-set will result in
 {{{manage_categories}}} being used.
  * {{{manage_cap}}} - Assigning the Term to a Post object
  * {{{edit_cap}}} - Addition & Modification of a Term
  * {{{delete_cap}}} - Deletion of a Term

 Note, That this doesnt affect plugins, plugins still have free roam over
 the taxonomy API regardless of the user logged in.
