Rewrote version listing system
Rewrote version listing system

Now sorts correctly in all instances and prints highlights
even in sorted views. Also will output a list of matching versions
for commands of the form nvm ls 0.4* rather than just printing one
version. nvm version 0.4 still prints the single latest matching
version, however.
