Added an important note about what Dataset_File.url means / contains.
If we can't save the downloaded file where we expected to, log it.
Adding new versions from Buildout.
Adding naive Travis config.
Setting up mime.types for Travis.
Removing unnecessary dependencies for Travis.

Using Python 2.6 to avoid distribute bug.

When using Distribute (rather than setuptools) with Python 2.7, a socket timeout
will cause an uncaught exception.

homepage is not required to successfully build, but the exception halts the
build process.
Adding output of log after Travis failure.

Problem occurs in new environments (and in particular Travis CI tests).
