Final zenroom (#147)
* zenroom fixes Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * expl. defined the aiohttp package Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * increased version number and fixed a zenroom runtime bug Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * added fialing zenroom tx signing test Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * extended test to pass zenrooom validation, but to fail planetmint validation. Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * added manual tx crafting Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * added zenroom fulfillment verification Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * the last mile before integration Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * zenroom unit tests are passing Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * simplified zenroom unit tests Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * removed obsolte lines from the zenroom tests Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * fixed acceptance tests Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * adjusted zenroom integraiton tests Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * fixed linting errors Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * simplified zenroom unit test Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * increased version number Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * using cryptoconditions without print message Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * increased cc usage to 0.9.9 readded daemon proceses Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * increased version to 0.9.6 Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com> * fixed deployment issue for 0.9.6 Signed-off-by: Jürgen Eckel <juergen@riddleandcode.com>
