Revision 279

Implemented new form of delimiters like this:

<tag>
	<delimiter>, </delimiter>
	<value>200a</value>
</tag>

which is equivavelnt to following old mark-up:

<tag delimiter=", ">200a</tag>

but, it won't loose spaces in attribute values (which
are invalid by XML specification and XML::Simple removes
them so WebPac never get them)
