db:generate should output colorless name of file when piped

[hkdobrev]

When you generate a migration file with db:generate command often you want to copy it to the clipboard or open it in your editor.

It would be really useful to ease that.

The command could detect when it's piped (the output is being passed to another command with a | pipe character). Then it should not use colors and should only output the name of the file.
