setup.py fixes
setup.py fixes

* it is executable now;
* license metadata should be short string according to
  http://docs.python.org/distutils/setupscript.html#additional-meta-data
* setup.py is now using  setuptools/distribute instead of distutils because distutils
  doesn't support 'install_requires' so it is necessary to either
  switch to setuptools/distribute or use 'requires';
* data_files are removed (they'll place LICENSE to some random place and that's not what
  most people want);
* django import is removed - it is not used and can prevent installation from
  requirements file in clean environments because pip calls 'setup.py egg_info' before
  installation.
