phing -> phar package task

Hi @farazdagi, @Pawka,

I see the issue #16 and I propose the phing phar task.

To achieve this result I have also removed the symbolic links and fixed configs files. In this way the side effect of "up, update, build" is the same but without symlinks.

```
phrozn.phar up
phrozn.phar update
phrozn.phar build

phrozn.phar init
phrozn.phar initialize
```

Bye
Walter
