[hibernate-dev] Updated information on Hibernate.org

[Steve Ebersole]

I just pushed changes related to new CI environment and (not so) new 
Jira url:

http://www.hibernate.org/issuetracker
http://www.hibernate.org/build

(from what I can tell someone previously tried to update the 
'issuetracker' page as well, but forgot to "activate" the changes...)

Let me know if you see the out-dated info anywhere else on the website.
