Version 1.1.1

- Separated the actual DVB hardware OSD implementation from the abstract OSD
  interface. 'osdbase.c/.h' now implements the abstract OSD, while 'dvbosd.c/.h'
  is the actual implementation for the DVB hardware. This is in preparation for
  allowing additional kinds of OSD hardware implementations.
- Fixed leftover references to the file FORMATS in MANUAL and svdrp.c.
- Avoiding ambiguities in the cList template class in case one defines a "list of
  lists" (thanks to Stefan Huelswitt).
- Simplified the basic cMenuSetupPage class for easier use in plugins.
- Added setup parameters and a Setup menu to the 'hello' plugin example.
- Fixed logging error message for unknown config parameters in plugins.
- Rearranged cleanup sequence at the end of the main program.
- Adapted PLUGINS.html to use the actual code examples from the 'hello' plugin.
