[MTOS-dev] Patch for missing metavars

[Víctor R. Ruiz]

  Hi:

  Template Loop Meta Variables (__first__, __last__, etc) are available
in dynamic publishing but just for mt:loop and mt:for blocks. Attached
is a patch which adds support to mt:entries/pages, mt:categories,
mt:tags, mt:authors and mt:blogs. A test template is also attached.

  Greetings,
