Properly quote password created during installation
When first installing freenas 11 (and 9 I believe), setting the root password truncates it to the first space. For example, entering "the quick brown fox" causes the root password to be set to "the" instead.
When changing the root password later through the console utility, passwords containing spaces are handled correctly.
Go through and do some proper quoting for passwords so we can
get passwords with whitespace properly set at install time.
