SVN:Fix could not be put into body of commnet editor at code history view
issue: Fix an exception while posting many issues

Reason: Every issue posting requires updating of project.lastIssueNumber
and it may occur OptimisticLockexception if the project.lastIssueNumber
has been changed already by other issue posting.

Solution: In project.increaseLastIssueNumber(), do not update self but
the project just fetched from database by Project.find.byId()

To make the solution works correctly, I did following works as well:

1. Add getter or setter to access the lastIssueNumber field. The
   increaseLastIssueNumber method cannot update lastIssueNumber directly
   because Ebean does not set the project to dirty even if the method
   modified the field.  When a private field is accessed directly
   (Ebean's "Field Access") in a static method or the other instance's
   method, Ebean does not call preSetter and/or preGetter so the
   instance will not be set to dirty.  I guess it is a bug of Ebean.

2. Refresh project before updating it, as the fixing of
   test/controllers/IssueAppTest.java in this commit. Posting an issue
   makes every project instance to have smaller lastIssueNumber than the
   actual value stored in database.

3. Make project.increaseLastIssueNumber static. It looks unnatural that
   non-static project.increaseLastIsseNumber method does not increase
   lastIssueNumber field of self.

4. Apply these fixes to Posting too.
Changes width of `Commit Date` column on `Code` > `Commits` tab.

Cause:
`Commit Date` column is narrow in width so its contents can not be fitted to one line.

Solution:
`Commit Date` width is stretched.

Changes widths of `Branches` and `Latest Commit` column on `Code` > `Branches` tab.

Cause:
`Latest Commit` column is narrow in width so its contents can not be fitted to one line.

Group admins or members are listed on issue's Assignee list.

Cause:
There is VOC.
When writing an issue on a protected project, we need to assign the issue to someone who is group member. But assignee list includes only project members.

Solution:
This already has been solved. 1ba9698
But there is a bug that Group admins are not listed on private project which has a group.
So group admins are added to assignee list on private project's issue.

User: removed synchronized block

User.visits() methods uses synchronized block to prevent the optimistic locking exception.
However, this can cause thread congestion, and it can be the reason why some requests
are handled very slowly sometimes.

So, I've removed the block and uses refresh() before update RecentlyVisitedProjects object.

Avatars of members and number of members and watchers in projects will be displayed on group pages if current user has suitable authorization.

Issue:
Only public projects show avatars of members and number of members and watchers on group pages.

Solution:
If an user has proper authorizations, these will be shown despite non public projects.
