Added chr13-optimizations (thanks to Christian Tusche / closes #39)

- increased efficiency in drawing list items in the main menu
- introduce relative Pos and Size of objects to given BasePos, BaseSize
  (used to draw list items)
- increase skin file version to 1.1
- the position of list items is interpreted relative to the "list" container
  when file version >= 1.1
- when a position is specified for "block" elements, the position of all
  contained elements is interpreted relative to the container position
- selective update of changed objects
  refresh can be controlled for individual objects by the attributes
  "refresh" and "changed"
  default behaviour is to redraw everything (compatible with old skins)
- moved state tracking of marquee, blink, scroll from cText2SkinRender
  to cxObject
- fixed use of Update.Lock() in render.h
- new: dynamic width/height of objects
- new: Option "bgColor" used for items "Text", "Marquee", and "Blink".
- remember period to next timeout when doing a non-timeout refresh
  prevent occasional start/stop of marquee-text
