Dpl: Add deployment option for FTP

[Stevoisiak]

Currently, the recommended methods for deploying to an FTP server from Travis CI is either to write a custom shell script or run a curl command in the 'after_success' section.

It'd be nice to have FTP supported as a deployment option. A minimal configuration for .travis.yml could resemble the following.

deploy:
  provider: ftp
  host: ftp://sitename.com/directory/myfile
  user: "FTP USERNAME"
  password: "FTP PASSWORD"
  skip_cleanup: true
  on:
    branch: master

I don't think this issue should be closed. How can I re-open it?
