toBoolean not fired for cli arguments

[lc-thomasberger]

BUG

When config options are passed in as cli arguments during installation, the toBoolean hook is not executed. This can break installation in lib/mailer as you can not disable certain config options.

Expected Behaviour

Boolean config options should always be properly converted into boolean regarding of there input type.

I think the config module should handle the conversion of y/n into true/false.

This is due a limitation of prompt -- we had the same problem with the config.json overrides (See install.js#L273 for a similar issue with y/n/true/false)
