1. wxShell fixes: now really uses shell (it wasn't different from wxExecute!)

and also added a version which captures the programs output
2. fix for compilers which have void ftime() (my mingw does) in timercmn.cpp
3. updated console sample to test wxShell/wxExecute
4. treetest now can toggle images or change their size
5. wxTreeCtrl doesn't crash if it has no image list
