Deploy Mainframer binaries to GitHub releases.

[artem-zinnatullin]

Since we now use compiled language #191, we need to ship binaries instead of source code.

To do that I'm planning to deploy resulting binaries to GitHub releases which can be either manually downloaded or installed through Homebrew/etc. Later we could also upload binaries to Bintray to have them there just in case.

As a reference example, this is how ripgrep does it:

• ripgrep GitHub releases page
• ripgrep Homebrew
• ripgrep Travis config that deploys to GitHub

And Travis documentation about deploying to GitHub releases https://docs.travis-ci.com/user/deployment/releases/

@ming13 I'm thinking about deploying 3.0.0-alpha-1 so we could start preparing Homebrew formulae #32 , #185 and you could start dogfood using Rust version at Juno

So then later we could deploy update with #188 or #189 and check update mechanism

wdut?
