  'include_file' statement: Re-introduce relative file paths

During the preprocessor migration, it seems the support for relative
file paths was lost.  This commit re-introduces all the lost features:

    * allow relative-path imports, e.g. include_file "cgrates.cfg".
      These file paths are considered to be relative to the .cfg file
      that is importing them

    * prioritize any relative-path imports found in the startup
      directory
      (Note: this is different from the "-w" working directory!)

    * detect infinite "include_file" loops

Many thanks to Jonathan Hulme for discovering and reporting this issue!
