Partial fix for issue 27:
  Add a '%!currentfile' special (internal) command.
  This command is used to track the recursive includes.
New macro %%CURRENTFILE, similar to %%INFILE, but reflects the current file being read during parsing. This is specially usefull when using the %!include command, so you can know from which file those contents are.
Partial fix for issue 27:
handle image in recursive includes
Needs Python > 2.6 for relpath method
Final fix for issue 27
  Correct test suite : include-nesting-folder include-nesting-folder-back
Creating a branch of trunk for fixing issue 27. These changes will be back to trunk after the 2.6 release.
Undoing changes commited in r338, r339, r340, r341 because they can't appear in 2.6 release due no more testing/documentation time left. These changes were saved in a separate branch in r342.
