Remove keys from authorized_keys in-place

This will speed up the rm-key operation. The downside is that
authorized_keys will not shrink when you remove a key. If this ever
becomes a problem it can be fixed by running 'rake gitlab:shell:setup'.

See merge request !66

Add a note that changing example configuration files requires changing omnibus-gitlab.

Keeping track of changes in these files is not easy and they usually require change in omnibus-gitlab.

Added a note so everyone is aware of this.

Similar is added to gitlab-ce and gitlab-ci.

Discussed in gitlab-org/omnibus-gitlab#605

Prevent character encoding issues by sending received changes as raw data.

Better alternative to !64 that doesn't require new gems and leaves dealing with string character encoding to gitlab-rails. See gitlab/gitlabhq!1701 for the corresponding changes there.

Correct spelling: Symlinking is short for symbolic linking

Remove recursive commands from bin/install

It is not clear what we need these for anymore. Because these commands
would recurse once through all existing files in all Git repositories,
and then another time through all directories these commands could
take very long on a server with a lot of repositories.

We keep the 'chmod' on config.repos_path, to deny world access to all
files and directories beneath it.
