Enhancement: Use consistent phrasing in menu and display

[moshekaplan]

After running the files search from "Tools-> File Search by Attributes", it seems inconsistent that the command is "File Search by Attributes", the tab states "File Search Results", and the window title underneath is "Filename Search Results". Ideally, one consistent phrase should be used. FWIW, my vote is for "File Search", as that seems simplest and clearest.
