the - was being identified as the url.

password.

Testing an empty URL instead of an empty password

This has two main advantages:

1.
If you use an anonymous FTP server for testing, the login with an empty
password succeeds and this test fails.

2.
An empty URL results in an earlier error message that doesn't involve a
network connection. This saves 20 seconds (invalid password timeout) in
my testing setup.
Adding Travis support

Travis (http://travis-ci.org/) provides free integration testing hooked
into GitHub. Writing this config file (.travis.yml) is the most
difficult part in setting it up. There are only three steps left:

 1. Sign into Travis with your GitHub account
 2. Activate GitHub webhook for this project
 3. Merge this pull request

Only one test will fail unless pull request #136 got merged.
Merge remote-tracking branch 'git-ftp/develop' into develop
Merge branch 'test_overwrite_defaults_by_scopes_emtpy_string' into develop
Merge pull request #136 from mkllnk/test_overwrite_defaults_by_scopes_emtpy_string
