Version 1.1.0vdr-1.1.0

- Begin of the 1.1 development branch. THIS IS NOT A STABLE VERSION!
  The current stable version for every day use is still the 1.0 branch.
- First step towards a universal plugin interface. See the file PLUGINS.html
  for a detailed description. The man page vdr(1) describes the new options '-L'
  and '-P' used to load plugins. This first step implements the complete "outer"
  shell for plugins. The "inner" access to VDR data structures will follow.
- The VDR version number is now displayed in the title line of the "Setup" menu.
