• Updates the README.md with info about how to install the package using AUR

@Ziul The best practice in the go universe says that relative path are not the go way. Every package should have a unique import path and be imported everywhere using that same import path. HOWEVER, it does work. @vovimayhem what say yo?

@thelastinuit That was something that really bothered me. The great motive for this PR was to include the plis-git on AUR, but I would need to build the package on local to the user. The way it was, I would make symlink from ~/ to some random path (probably /tmp), then go get to download plis, so then build it locally. It's madness the package to be self dependency. I asked two other AUR's maintainers what they think about it. Both reproved the way the package was doing. To be honest, that was my first program on Go that a touch, and i got surprised that ../ did the trick, but if there is a better way to do it avoiding the symlink, I will be OK with it.

I think, take it with a grain of salt, there is a way with the latest updates but I'm not sure. Personally, I would accept the PR JUST to see it in AUR... it would be so badass. Let me get back to you @Ziul alright?

[Ziul]

Sure!
