JWT security

Page http://localhost:8080/api/hello is secured. To access this page, you need to do the following:

POST request to http://localhost:8080/api/signup with body
```
username: "user",
password: "12345"
```
POST request to http://localhost:8080/api/auth, then take token from responce and use it in header to access secured page
GET request to http://localhost:8080/api/hello with header:
```
x-auth-token: <your token here>
```

Security is based on AuthenticationTokenFilter:

@Override 
public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) 
             throws IOException, ServletException { 
  HttpServletRequest httpRequest = (HttpServletRequest) request; 
  Authentication authentication = authenticationService.authenticate(httpRequest); 
  SecurityContextHolder.getContext().setAuthentication(authentication); 
  filterChain.doFilter(request, response); 
  SecurityContextHolder.getContext().setAuthentication(null); 
}

And some services for Token creation and Token verification.
