let's drop the 64 chars part title limit, please

[Tim Gould]

I've just written my own version of mklist that can replace overly long lines by unique (with a caveat unlikely to be needed) short-hand identifiers. So if I can get it compiled on windows and tested properly we don't need to worry as users can simply demand that their Parts.lst file is restricted to 64 characters.

Will attach code elsewhere for anyone in possession of a C++ compiler.
