Status bar should expand to window width instead of truncating filename

[Gingerbread Guy]

In this example, I can't read the filename because it doesn't fit on the thumbnail or the status bar. It also looks like XnView Classic made better use of the space; XnView MP wastes about 50% of the window width on blank space. I fixed it by adding maxCharsFilename=256 to the [Viewer] section of xnview.ini
