Fix case where state != enabled causes error

When using the register_site state, if the `state` for the
site in the apache pillar did not equal "enabled" the error

```
Cannot extend ID 'a2ensite <name>' in 'base:apache.register_site'. It is not part of the high state.
```

If statements were there to build out the `a2ensite` or `a2dissite` ID
appropiately, but the next state for managing the config always
assumed that the `a2ensite` id would be there.

Addressed by making a Jinja variable that will be the appropiate ID,
probably could use a better name.

This reverts commit f7b14ec169.

Don't execute a2ensite if the vhost is already enabled

Fix link to instructions

The link to the installation and usage instructions does not work. This fixes it.

The structure of this example file was quite confusing. Most of these
values are not required and should be denoted as such. Jinja notiation
to denote re-used Pillar values was also a bad and confusing choice.

Closes #8

Having multiple different examples in the same file was causing
confusion.

Fix typo

Fixes #22
