YobiUpdate: Use repo.yobi.io as the update repository
PullRequest: Fix server error when conflict occurs

Reason: NPE occurred when a merge conflicts because Yobi tries to get
the number of the merged commits even if the list is null.

Solution: Set the list of commits Yobi tries to merge even if the merge
conflicts.
Notification: Use system email address as notification sender

Problem: Many Yobi users had extracted and filtered notification
messages of Yobi from their mailbox by using MUA which supports
groupping by the sender's email address. But if
application.notification.bymail.hideaddress is false, it did not work
because the sender's email address is the user's who causes the
notification.

Solution: Use system email address as the sender's email address of
notification messages even if
application.notification.bymail.hideaddress is false.

shows a alert view when site admin removes a member who is only a project's manager.

Cause:
When the site admin removes a sole project's manager on a project, any alerts or messages did not occur. The delete method is called by AJAX but Yobi server returns redirect response. It can not show alert view related to `flash method`.

Solution:
Proper HTTP response codes was added and a error callback function was inserted to javascript codes. The callback function will compare responses and if the reponses are 401 or 403, current page is reloaded to show a alert view.

Private-issue: 1659
Shows non-member assignees on assignee dropbox.

Cause:
If a member is removed from a project after the member is assigned to an issue, the member is not listed on assignee dropbox. Because assignee list contains only project and group members.

Solution:
Although some assignee are not member of projects and groups, those will be shown on assignee dropbox because of assignees.
