Rename (or add) repository for homebrew

[ryanlevy]

I'd like to suggest making a homebrew tap repository for all ALPSCore codes
The full explanation is here, but in short: if we make a repository named homebrew-tap then a user simply has to use brew tap alpscore/tap and then they'll have all the formulas that we maintain, without waiting for pull requests.

For example, see my maxent tap.

IMHO it is a good idea. Yet having stuff in homebrew-science has a perk of being automatically tested for all current Mac OS versions. So I'd say, it's better to leave alpscore itself where it is, while having a tap for all new codes.

Since homebrew/science got discontinued, we indeed need to make a separate tap for ALPSCore.

Good point. @galexv, can you prioritize this once our Jenkins installation is done?

Yep. Self-assigned now. :)
