Use the py27-GitPython package when installing GitPython on FreeBSD

Use the py27-salt package when installing salt-ssh on FreeBSD

This key defaults to a value of `python-git`.

On FreeBSD salt-ssh gets bundled into a single package with the other
SaltStack components (minion, master, etc.).

Add support for GitPython and salt-ssh on FreeBSD masters

Done at the maintainer's request.

salt.api state fails

Seems there are several colons missing for salt.api to work correctly, hope I found all of them

This change tweaks the GitPython package installation state to support
alternate package names (on FreeBSD, it's called "py27-GitPython").
Also, on FreeBSD salt-ssh is included in the "py27-salt" package by
default, requiring an update to `distro_map`.

Fix stuff suggested by @iggy.

Updated master.d/f_defaults for 2014.7

Fix syntax error

Fix syndic requisites

The syndic service was depending upon itself, which caused the salt run
to fail. This commit fixes that by depending on the salt-master service
rather than the salt-syndic service. I also made it more general by
using IDs to specify the provider rather than the name, which is a bit
less reliable.

Remove Duplicates from defaults.yaml and map.jinja

fix empty formulas list in pillar with empty dic.

Fix pillar_roots configuration format in master

This commit fixes how `pillar_roots` are generated and after this fix the
generated configuration does not contain any unnecessary new lines:

```yaml
pillar_roots:
  base:
     /srv/salt/dir1
  dev:
     /srv/salt/dir2
     /srv/salt/dir3
  locale:
     /srv/salt/dir4
```

Before this commit the pillar_roots in `f_defaults.conf` for master would be
generated with a lot of empty lines in between directories, like this:

```yaml
pillar_roots:

  base:

     /srv/salt/dir1

  dev:

     /srv/salt/dir2

     /srv/salt/dir3

  local:

     /srv/salt/dir4

```

The minion configuration is not affected and renders fine.
