Leading hyphen in log file names

Not sure if this is yet a violation of posix but probably not the right behavior (http://www.dwheeler.com/essays/fixing-unix-linux-filenames.html#dashes http://www.opengroup.org/austin/docs/austin_224.txt ).

Am not competent to suggest best fix but easy first pass that preserves approximately equivalent randomness is just:

// lib/forever.js line 325

options.uid = options.uid || utile.randomString(4).replace(/^\-/, 'H')

If you are in touch with the utile developer might be nice to have optional chars argument for cases like this.

utile is kind of sophisticated and nice, don't want to muck up but maybe will try a simple base32 option for keyboard- and shell-friendly filenames. Thanks AvianFlu.
