Added brougs78-extensions (thanks to Andreas Brugger / references #39)

- added tokens for the next 3 timers:
  CurrentEventsTitle[123], CurrentEventsStartDateTime[123],
  CurrentEventsStopDateTime[123], CurrentEventsChannelNumber[123],
  CurrentEventsChannelName[123], CurrentEventsIsRecording[123]
- added audio- and video-tokens:
  PresentLanguageCode, PresentLanguageDescription, PresentVideoAR and
  implemented the missing code for the Language-token
- added tokens for replay:
  ReplayName, ReplayDateTime, ReplayShortText, ReplayDescription,
  ReplayLanguageCode, ReplayLanguageDescription, ReplayVideoAR
- additional recording-tokens:
  RecordingVideoAR, RecordingSize
- added a reset for scrolling text (configurable)
- added recording-tokens:
  RecordingLength, RecordingCuttedLength
- added tokens:
  OsdWidth, OsdHeight
- switched the search-order for the fonts to priorise the skin-folder
  (this avoids error-messages in the log)
- added the possibility to have a scrollbar in every menu - not fully
  implemented yet (to position in menu-lists is not necessarily correct,
  if there are more items with the same osd-text)
- added a configuration option for showing the scrollbar in the menus
- added token TimerConflicts using the service interface of the epgsearch
  plugin "Epgsearch-lastconflictinfo-v1.0"
- added a test-feature to search for reruns of a program and add the
  information to the extended epg-info (trigger DEVELOPMENT_FEATURES).
  This uses a service interface of the epgsearch plugin
  "Epgsearch-searchresults-v1.0"
- the extended epg-info and the recording-info are extended by AUX-Infos
  (configurable)
  there is also an option to strip known tags
- the tab-widths are scaled for taking into account that different TT-Fonts
  have a different width than the default font from VDR
- added tokens for signal-info:
  FrontendSTR, FrontendSNR, FrontendHasLock, FrontendHasSignal
- added token PresentEventID for EPG-images
- added tokens for recordings:
  RecordingFilename, RecordingPriority, RecordingLifetime
- set EditableWidth. This is important for plugins like 'rotor' or
  'extrecmenu'
