Tool for gh-pages deploing

Hello, Vadim
I've created tool for automatical deploing to gh-pages

## Usage
`make deploy`

## How it works
1. Create gh-pages branch for current repository

2. Create `_deploy` folder

3. Copy all files and folders of presentation into `_deploy`

4. Push content of `_deploy` to github.com


## How does it look
Open in browser: `http://yourName.github.io/project/` and enjoy your presentation :)
