ValidatorDate always accepts date format overflow

[fugerit79]

Imagine we have a date format configured like this :

	<validator id="testDateValidator" type="org.fugerit.java.core.validator.ValidatorDate">
		<entry key="dateFormat">dd/MM/yyyy</entry>
	</validator>

It will correcly parse input like

01/03/2021

But will not fail in case of overflow too , for instance :

01/03/2021AAA

We want to add an option to make the parsing strict, for instance :

	<validator id="testDateValidatorStrict" type="org.fugerit.java.core.validator.ValidatorDate">
		<entry key="dateFormat">dd/MM/yyyy</entry>
		<entry key="strict">true</entry>
	</validator>
