Adapted DMSLib download method to be more generic

Browse Source 
DMSLib now extends FHC Controller to use its new method 'outputFile',
which sets HTTP headers and reads the file.
DMSLib uses now download function to accept params from Controller like
own filename or special disposition.
Loading document and retrieving file info is outsourced into own method
to be reusable.
