Added a few new features

[leo-arch]

Hi @jhawthorn. First of all, great work! Simple, lightweight, hackable, and written in C.

Straight to the point. I added a few new features:

• Multi-selection. There's a previous pull request for this, but was never merged.
• Results/matches/window left padding
• A few command line switches to modify standard TAB, left, and right arrow keys behavior
• Cyclic scrolling (defaults to disabled)
• Pointer and marker customization
• Basic color support (it runs colored by default now, but you can disable colors via --no-color). Colors are customizable via a specific environment variable (FZY_COLORS).

I've tried to document all this in the manpage as detailed as possible.

I can guarantee it works. I'm using it myself as an alternative TAB completion mechanism (using the above features to perform the integration) for my file manager (CliFM): it supports readline's default completion, FZF, and now FZY.

Though still experimental, you can try it running CliFM (latest git version) with the --fzytab command line option (it will look for the fzy binary in PATH).

Thanks for the extra features.
Could you please add cli option to output a different version infomation, so I could ditinguish your version from the original version? So I could implement different options in my scripts according to the version installed.

Time to create a fork of fzy. Maybe fzy-ng? :)

Considering that there seems to be some real interest on these new features, it might be a good idea.

As to the name, what about fzx? Short and easy to type. I looked for fzz, but there's another project using this name. Or maybe fzs; it's available as well (it might stand for either fuzzy searcher or fuzzy seeker). fnf (recursive acronym for fnf's not fzy) could also be cool.
