[win32] remove modelines_template.xml and kodi.log from installer package
[win32] Make sure we copy the userdata from the build into the $INSTDIR/userdata". Since we only use the userdata from $APPDATE/${APP_NAME}/userdata/ or portable_data it's safe to wipe $INSTDIR/userdata.
[win32] Update installer text to be more clear about taken actions. Also set artwork for un-installer pages
