A test was broken if running on a non-standard port.
Made checking for (non-)standard port more robust.
Changed gitlab_on_non_standard_port to gitlab_on_standard_port (less negative).

Before this commit gitlab-shell but me placed directly in home dir.
Ex:
  /home/git/gitlab-shell

After this change you can place gitlab-shell in custom location.
Ex:
  /Users/developer/gitlab/gitlab-shell

Any mention of Issues, MergeRequests, or Commits via GitLab-flavored markdown
references in descriptions, titles, or attached Notes creates a back-reference
Note that links to the original referencer. Furthermore, pushing commits with
commit messages that match a (configurable) regexp to a project's default
branch will close any issues mentioned by GFM in the matched closing phrase.
If accepting a merge request would close any Issues in this way, a banner is
appended to the merge request's main panel to indicate this.

-If not specified in the gitlab.yml default this setting to false

Hackily handle this with a begin block and return a default that matches current use.

Instead of assuming that the Settings.gitlab['user'] home directory is:
/home/git

Obtain the default value from Etc and use that if not set in config.yml.

“Can create groups” and “Can create teams” had hardcoded defaults to
`true`. Sometimes it is desirable to prohibit these for newly created
users by default.

This option allows to disable users from changing their username.

This is very usefull in environments using strong internal authentication methods like ldap, pam or shibboleth.

You can allow users to change theyr username in these environments, but then new users (users loging in first time) is blocked from gitlab is her username exists.

error is that ```enabled ||= true``` always evaluates to true.
Change all initialization of bool settings to use the same syntax:
```setting = true if setting.nil?```

The tasks gitlab:env:info mixes user and group, and presume as a group 'git'.
However, gitolite group name can be anything.

That patch add the git group name in the config,
and check gitolite.ssh_user group against git.group
(which defaults to 'git', as before this patch, if undefined).

M config/gitlab.yml.example:
  Add 'group' in 'git' section
  Mention default value for the two extra settings
M lib/tasks/gitlab/check.rake:
  Check that gitolite.ssh_user *group* is the one defined in git.group.
  Make sure to default to 'git' as the expected group
    if said group is undefined in the config.
  Note: uses a more complete regexp for the group detection
        (the group can start, end or be in the middle or the list of groups
         of gitolite.ssh_user)
M: config/initializers/1_settings.rb:
  Add default values for gitolite.group and gitlab.user

All overrides are marked as deprecated.
Default settings are at the bottom.
