misc/permission.png and misc/configure.png are missing

In modules/system/system.css there are 3 images used in module list:

.more-help-link a, a.module-link-help {
  background: url(../../misc/help.png) 0 50% no-repeat; /* LTR */
}
a.module-link-permissions {
  background: url(../../misc/permissions.png) 0 50% no-repeat; /* LTR */
}
a.module-link-configure {
  background: url(../../misc/configure.png) 0 50% no-repeat; /* LTR */
}

help.png exists but permissions.png and configure.png do not.
