Split up newsite

nginx/sites/configs/cache.conf:
*Change quotes to double ticks to prevent issues with nginx.

newsite.sh:
*Changed explanation in database creation prompts. Was asking for MySQL password, not database user password.

*Split up the installation process into separate steps so I can check permissions on the folders before trying to actually install WP.

*Correct syntax errors with statements so the script performs as expected.
