#44 Add support for including an autogenerated share password

[Mike Burns]

We'd like to see support for providing an autogenerated share password when sharing a file or upload request. We've decided here that it's OK for the password to be included in the same email as the shareId URL. We'd like to see configuration options for enabling this sort of feature for sites that want to do that.

Included are two sets of diffs that provide this functionality using the Server Config admin interface. One for including the password in the email to recipients and one for autogenerating the password. The autogenaration code is the same as that used to create the shareId. I'm not sure I updated the footer.tmpl file in the best manner to not display the password form, but it works.
