#2 Images and file links markup improvements

[MoMaT]

It would be nice if images included with icon tag have
width and height automatically detected (using some
java image library like ImageInfo -
http://www.geocities.com/marcoschmidt.geo/image-info.html\).

In case of file links the size of file could be
automatically checked and given in a markup. I got two
suggestions. Giving this in title, which is less code
invasive but well somewhat hidden on the site:
<a href="xxx.zip" title="15.2kB">link name</a>
or giving it in a classed span where the presentation
is style dependent:
<a href="xxx.zip">link name<span
class="FileSize">15.2kB</span></a>
It also would be nice if this file size presentation
could be disabled in config.xml.
