system/grub4dos: Added (bootloader based on GNU GRUB)

GRUB4DOS is a universal boot loader based on GNU GRUB with bugfixes
and new features such as built-in BIOS disk emulation, ATAPI CDROM
driver, and Chinese support. It can be loaded from DOS/LINUX,
via Windows boot manager/syslinux/lilo, or from MBR/CD.

+driver, and Chinese support. It can be loaded from DOS/LINUX,
+via Windows boot manager/syslinux/lilo, or from MBR/CD.
+
+To build the Chinese version, run the script like this:
+CHINESE="yes" ./grub4dos.SlackBuild
+
+This package does not conflict with the Grub package in /extra.
+It is safe to have both installed.
+
+Note: this will not build on x86_64.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
