on top of #1525, so review/merge that one first.\r\n\r\nThis PR changes the way we've been storing files: instead of adding a prefix with the artifact_id, it creates a folder for the artifact (named with the artifact id) and it moves the files in such folder.\r\n\r\nSince moving the files to support this new structure will be expensive, we leave the old mountpoints working in the old style while, the new mountpoints (based on the artifact type) follow the new structure. This means that the code has to be back-compatible (yay!) which adds a bit of complexity in the functions dealing with files.\r\n","created_at":"2015-11-06T06:03:53Z","updated_at":"2015-11-09T22:43:46Z","closed_at":null,"merged_at":null,"merge_commit_sha":"a4fa742458909fd14fedea998964d075e3a7ccf5","assignee":null,"milestone":null,"commits_url":"https://api.github.com/repos/biocore/qiita/pulls/1527/commits","review_comments_url":"https://api.github.com/repos/biocore/qiita/pulls/1527/comments","review_comment_url":"https://api.github.com/repos/biocore/qiita/pulls/comments{/number}","comments_url":"https://api.github.com/repos/biocore/qiita/issues/1527/comments","statuses_url":"https://api.github.com/repos/biocore/qiita/statuses/ed56518903d5b7503f66a4b806294f0c2ecb3bf9","head":{"label":"josenavas:artifact-obj","ref":"artifact-obj","sha":"ed56518903d5b7503f66a4b806294f0c2ecb3bf9","user":{"login":"josenavas","id":2501478,"avatar_url":"https://avatars.githubusercontent.com/u/2501478?v=3","gravatar_id":"","url":"https://api.github.com/users/josenavas","html_url":"https://github.com/josenavas","followers_url":"https://api.github.com/users/josenavas/followers","following_url":"https://api.github.com/users/josenavas/following{/other_user}","gists_url":"https://api.github.com/users/josenavas/gists{/gist_id}","starred_url":"https://api.github.com/users/josenavas/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/josenavas/subscriptions","organizations_url":"https://api.github.com/users/josenavas/orgs","repos_url":"https://api.github.com/users/josenavas/repos","events_url":"https://api.github.com/users/josenavas/events{/privacy}","received_events_url":"https://api.github.com/users/josenavas/received_events","type":"User","site_admin":false},"repo":{"id":13527677,"name":"QiiTa","full_name":"josenavas/QiiTa","owner":{"login":"josenavas","id":2501478,"avatar_url":"https://avatars.githubusercontent.com/u/2501478?v=3","gravatar_id":"","url":"https://api.github.com/users/josenavas","html_url":"https://github.com/josenavas","followers_url":"https://api.github.com/users/josenavas/followers","following_url":"https://api.github.com/users/josenavas/following{/other_user}","gists_url":"https://api.github.com/users/josenavas/gists{/gist_id}","starred_url":"https://api.github.com/users/josenavas/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/josenavas/subscriptions","organizations_url":"https://api.github.com/users/josenavas/orgs","repos_url":"https://api.github.com/users/josenavas/repos","events_url":"https://api.github.com/users/josenavas/events{/privacy}","received_events_url":"https://api.github.com/users/josenavas/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/josenavas/QiiTa","description":"QiiTa
