Add encrypt & sign option, remove archive_HelpMessage()

`archive_HelpMessage' was removed because variables from `archive' sub
are not shared with it.

On #perl@freenode:
    <andinus> i have a sub archive_Help inside of sub archive, when i try to
              use archive's var in archive_Help perl says "Variable
              "$archive_dir" will not stay shared at..."              [02:55]
    [...]
     <Grinnz> generally, you pass variables into subs that you call   [02:57]
     <Grinnz> defining a sub within another sub is evidence that you did it
              wrong
    [...]
    <andinus> is defining a sub within a sub not a good idea?
     <Grinnz> it does nothing useful                                  [03:01]
