Default Value for Unset Dynamic Value Mode

Users should be able to set a system property to control the default behavior for dynamic values in the case where no property has been set.

Per default this value is 'allow', so that users get no constraints.

Some users may prefer to start with 'lenient' or another mode. With 

de.smartics.projectdoc.dynamicValue.mode.initDefault

set as a System Property, users may now set the default.

In case a default value is set, but not understood (misspelled), the default will be 'lenient', not 'allow'.
