Change default behaviour

[ethicalhack3r]

THESE ARE BREAKING CHANGES

Change 1

Currently we run a bunch of things when supplying no arguments.

The proposed change would not run anything when no arguments are supplied, and only run enumeration and other things when the additional arguments are supplied.

Change 2

Currently the default enumeration modes are "mixed", with the exception of plugin enumeration, which is "passive".

A lot of users don't read the documentation before using WPScan and miss this.

The proposed change would change --plugins-detection default to mixed.
