added a new syslinux menu splash screen, I'm not an artist
but I think it is better than the generic splash which was
already included. Also added the svg file if anyone wants
to make any changes.
change MILISECONDS to SECONDS. Syslinux actually uses
tenths of seconds not milliseconds, but it seems
unnecessary to expose this to the user. Fix templates
to only specify the timeout once.
share more code.
Change pxelinux directory setup to match debian installer
Change syslinux templates to use {$VAR} syntax so the
templates are easier to read
Remove etch support for syslinux, since INCLUDE syntax
is not available in etch syslinux v3.31
A new common template called help.cfg has been included to avoid help
keys to be duplicated while prompt.cfg has been changed to be specific
to each mode since it has different requirements for initial text to
be displayed.
Other minor fixes were also been done during the spliting and then
included on this patch too.
All files from syslinux-menu templates directory has been moved to
syslinux/menu. lh_binary_syslinux had some changes to work with that
but they were minimal ones.
