Merge branch '187_automatic_releases' into 'master'

[CI] Add automatic build

- Add automatic binary generation for windows, linux and darwin
  + Binaries are pushed to http://static.lesterpig.com/dfss (tls will come soon)
  + The build is done ONLY in `master` branch AND on version tags
- Remove the use of "user.HomeDir", because it is not compatible with linux xcompilation
