Title: Long filename support for LCD display

It is a bit of a hack, but I added long filename support to the LCD display. The code still uses short filenames to find files, change directories and selecting files. But it can display long files. This uses the least amount of memory and has the least chance to break any code.

I'm using 27 bytes of extra RAM.

The GCode commands that deal with SD files still use short filenames. As well as the directory shown at the top of the menu if you enter subdirectories.
