foamDictionary: Added support for manipulating lists of dictionaries

- provides support for manipulating polyMesh/boundary

  - changed behaviour of disableFunctionEntries option to preserve
    #include

  - dictionary: added reading of lists of dictionaries.
    + each list element may be accessed using the 'entryDDD' keyword
      according to their list index.
