- added "hide" flag for MetaElem. Hidden MetaElem doesn't influence polygonisation.

  It is useful for large scenes, when you work with lot of MetaElems. Example:

  http://e-learning.vslib.cz/~hnidek/pics/deer.jpg

  (PildaNovak's model)

- shortcuts for hiding of MetaElems:
   H ......... hide all selected MetaElems
   Shift-H ... hide all unselected MetaElems
   Alt-H ..... unhide all hidden MetaElems

- items in header menu of 3dview
