and the usage of an ini-file, thus remembering window
positions and directories:
wguiRemoveAllHistory
wguiInstallHistoryIntoMenu
wguiInsertCfgIntoHistory
wguiDeleteCfgFromHistory
wguiPutCfgInHistoryOnTop
wguiDialogProc (some minor changes)
For the keeping track of window postions and applying the
last used position the function wguiEnter changed. Also
changes were need in the gfxdrv.c file since this file controlled
the creation of the emulation file.
