Copy read permissions on ComputedRelation rdefs Closes #5694110

[datafeed] fix typo in DataFeedXMLParser.is_deleted (closes #5729755)

[server/sources] make sure entity._cw is a Connection before calling Storages The storage callbacks don't get an explicit Connection objects, so they go through entity._cw to access the repo and schedule operations. Since that entity object comes out of the entity cache, its _cw may be a web request instead of a Connection. So fix it up around the storage callbacks. Closes #5753543

[hooks] base64-encode extid before inserting it into moved_entities If we insert the wrong value we're never going to find these entities again... Closes #5741105.

[hook] remove assumption about entity cache vs cw_edited We were assuming that if an entity is in the connection's cache, it has a cw_edited attribute. This doesn't seem to always be the case. At least in cubicweb 3.21, merging the web and repo-side caches makes this more likely, but Denis says he's also seen this on 3.20.

[hook] don't open-code Connection.entity_cache

[tox] Add missing dependency on webtest for devtools tests

[tox] Add missing dependency on webtest for wsgi tests

[tox] Remove set of PATH environment variable The : concatenation does not work actually so the resulting PATH was just wrong (it did not contain the previous PATH). Anyways, the PATH environment variable is passed by default by tox so it's probably better to let the caller set it (thus avoiding to hard-code the specific postgres version and path). http://tox.readthedocs.org/en/latest/example/basic.html#passing-down-environment-variables

[datafeed] also catch EnvironmentError when trying to load the cwclientlib config file means the config file has not been found, so fall back to the old implementation instead of crashing.
