* fix: always remove tmprepo, doh

responsibly. :P
* an --at option for add-repo for the position of repo to be inserted
in the list of repos. (we already got it in the API, this is just CLI)

  "application cd"s, let's give the users what they want :)

 - fix: equal must handle comparison with None
 - a small cleanup
 (more fixes to come)

evidenced by #2901 and countless other test suite bugs.

* fix: add sources to componentdb correctly, enabling 
  emerge <component> :)

* improve pisish a little

* fix (attempt): try to finalize api in case of error

command after the other (yes, it will have more features as requested)

packages again.
