[New] Added set-colors command. See details below:

Browse Source 
This command allows users to replace default colors with their own custom colors.

 - top-level commands modified: alias, ls, ls-remote
 - helper functions added: nvm_echo_with_colors, nvm_err_with_colors,
nvm_set_colors, nvm_get_colors, nvm_print_color_code
 - functions modified: nvm_print_formatted_alias, nvm_print_versions, nvm_print_alias_path (implicitly), nvm_print_default_alias (implicitly), nvm_list_aliases (implicitly)

We added tests and info on using this command to the README!
