Bug#841488: about index index.php

[Ognyan Kulev]

I think it would be clearer if the following line is removed from 
sites-available/default:

# Add index.php to the list if you are using PHP
And the following lines is added after "# pass PHP scripts to FastCGI 
server":

# (usually you also need to add index.php to the index directive above)

And related to #841230, please replace "php5" with "php7.0" also in the 
comments :-)

Best regards,
Ognyan
