Dump files prefixed with "Warning: Using a password on the command line interface can be insecure."

Causes database imports to fail.

I'm using MySQL 5.6, which has improved security, which might be the problem.

Fixed by modifying tpls strings to set password variable:

```
     mysqldump: "MYSQL_PWD=<%= pass %> mysqldump -h <%= host %> -u<%= user %> <%= database %>",

     mysql: "MYSQL_PWD=<%= pass %> mysql -h <%= host %> -u <%= user %> <%= database %>",
```
