Database import figured out, added swap

newsite.sh

Changed database import process to use mysql commands. Script will now also change the wp-config.php file to reflect the new table prefix.

All nginx configs:
Removed tabs and spaces while hunting down an error. I don't believe it was that, but its all working now, so I'll leave them out. Dang it.

installs.sh:

Added swap due to memory errors while working with sites.

sysctl.conf:

Added swappiness so swap is configured after reboot.
