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
