ToolTipForm.cs: make tooltip do not steal focus in Linux. 

Tooltip steal focus in Linux because the "WS_EX_NOACTIVATE" tag must be put to "STYLE" instead of in "ExSTYLE" (extended style)

NotifySection.cs: increase micro-delay for Chat layout-update. (because in Linux if multiple notification bar appears at same time  layout update doesn't appear to stack, so we add this delay to wait all of them appear first before doing layout update).
