LCD Perl Program, new feature plus cleanups.

[Davesworld]

One of the forum members here, Smartmlp took the lcd-0.8.1-cobalt here and added a text feature that behaves exactly as the Cobalt Panel Utilities /sbin/lcd-write does. Rather than lcd -text  and making sure you have something to fill the 16 characters, the command is lcd "first line" "second line" and any combination of spaces before or after the word will work as long as you do not exceed 16 characters and or spaces per quotation. Beyond what he did, I stripped the ixui and dsl subroutines out of it as well.

One of the benefits of the perl driver versus the Cobalt Panel Utility binaries is that it will allow text to be written very early in the init process whereas the Cobalt lcd-write binary will not text until the last services are being started. Also, with the perl program you can also text all the way down to halt with text telling you when to shut off power or that you are rebooting.

Next I'll likely prune the non working 4 bit functions as they were never completed and never worked as well as the fact that Cobalt lcd's are all 8 bit winamp wired parallel. It's a bit easier to read the file with things pruned out that don't work or are not used.

Still to do, buttons.
