zsh: Update fzf-tab 
Make use of colorful action groups and query input option.

By default, will group the different completion actions (if they have
been set up for the respective zsh completion) as different color sets.

When entering an input and nothing fits (or something else than
intended), it is now possible to simply hit alt+enter instead of just
enter to add whatever you typed into the zle instead of whatever fzf
provided you with (or nothing at all, if it didn't).
