1. a couple of compilation warnings fixed (strconv/listctrl)

2. now reenable windows disabled by wxWindowDisabler slightly earlier:
   this solves the problem with "wrong" window being brought to top and
   eliminates the need for BringWindowToTop() and SetActiveWindow() in
   our code
3. style wxFRAME_FLOAT_ON_PARENT is now obsolete and unused, all frames
   have WS_EX_APPWINDOW style and appear on the taskbar
