Change singular/plural handling in AgaviXmlConfigDomElement convenience methods

[david]

The automatic handling of <plurals> container elements with <plural> children is a bit random and incomplete at the moment. We should change it to behave like this (discussed on IRC):

• getChild() does no magic, returns exactly one child element of the given name if only exactly one child element of the given name exists
• hasChild() bool of the above
• getChildren() gets a third argument, defaulting to false, to switch on the singular/plural handling
• countChildren() and hasChildren() work the same way
• new get() and has() methods are shortcuts for calling getChildren() and hasChildren() with the third arg to true

Mind you we cannot use __get()/__isset() overloads for the plural magic as originally planned as the parent DOMElement and DOMNode classes define a couple of public properties already.
