Update bat.py

Having the url to download the pathogen directly in code and can not somehow url sobrecrever this was the cause of my problem, as the url that was fixed in the code was not possible to download the script since it is not available at that url.

Was even added a message to better identify impossibility of lowering the pathogen when running the command:

<pre><code> vimpyre init</code></pre>
Update bat.py
FIX: vimpyre init
