added simple upload test and fixed anonymous login

[mattnenterprise]

It looks like the tests are currently failing. Also for most rust projects I have seen tests at the bottom of the same file as the code that it tests. For example: https://github.com/hyperium/hyper/blob/master/src/status.rs Let me know if you have found some other documentation that counters that claim.

Usually unit tests go into the source files directly and integration tests go into a separate test file. I think this one looks more like an integration style test.

Fixed the test and the code. The "login" method did not handle anonymous logins... Now fixed. Ideally another test should test normal login.

Also, as for where the tests should be placed, it depends. Some crates have tests at the end of source files, others put them in separate files. I have seen recently a project using a separate "tests" folder (similarly to putting benchmarks in the "benches" folder), I like that as it makes the tests easier to find/modify, so I've done the same in this pull request.

I just found out that the Cargo documentation states that integration tests should go into a "tests" folder: http://doc.crates.io/manifest.html#the-project-layout

@mattnenterprise may I suggest you merge this PR or #36 ? @workanator has also fixed the problem with parsing PASV response, it's a pity that we both fixed the same bug :-/

[mattnenterprise]

@matt2xu I merged in #36. I would still like to keep your test if you are willing to fix merge conflicts.

[matt2xu]

@mattnenterprise alright, sure I'll fix the conflicts tomorrow.

[matt2xu]

Ok I rebased it and fixed the conflicts.

Thanks!
