(svn r6047) -Codechange: FOR_ALL now _only_ loops valid items, and skips invalid ones

Browse Source 
-Codechange: use IsValidXXX where ever possible
  Note: both changes to prepare for new pool system, which needs those changes.
  For every pool there are 2 ugly lines, which will be removed when done
  implementing new pool system.
  Based on FS#13 by blathijs, partly implemented.
