Local (DMZ) URL for gogs workers (such as ssh update) accessing web service. In
most cases you do not need to change default http://localhost:HTTP_PORT/. You
may need to alter it only if your ssh server node is not the same as http node,
eg. running behind proxy on different node than web server.

                     --- 80 public port -> 8080 -- web server node
                    /
    public proxy --<
                    \
                     --- 22 public port -> 10022 -- ssh server node

This option is not intended to be accessible via web GUI settings, since it is
unlikely someone needs to change it to somethings else than default
http://localhost:HTTP_PORT/ which should work for most of the cases.

But this should land into the documentation somewhere.

fixup

We can look at the PushCommits object to see how many commits were
included in a commit, and add some template logic to only show the
comparison link when there are at least 2 commits in a push. We also
correct the link to display the number of commits.

We have new tab, but we had no entry. That's why it was showing "code"
(lowercase) as this is text id, where we were expecting properly title cased
"Code" to be shown in English version.

Also add Polish translation "code=Kod".

Just some phrasing changes to make the English translations sound more natural.

Consider following LDAP search query example:

    (&(objectClass=Person)(|(uid=%s)(mail=%s)))

Right now on first login attempt Gogs will use the text supplied on login form
as the newly created user name. In example query above the text matches against
both e-mail or user name. So if user puts the e-mail then the new Gogs user
name will be e-mail which may be undesired.

Using optional user name attribute setting we can explicitly say we want Gogs
user name to be certain LDAP attribute eg. `uid`, so even user will use e-mail
to login 1st time, the new account will receive correct user name.

The hyperlink and the display name of the branch if the branch is in a folder or the branch name has '#'

This allows the admin to disable the version information about gogs and
go in use in the footer.
