Updates for release 0.1.0

[jtniehof]

This PR makes all changes relevant for the 0.1.0 release (first release!)

• Finish script shuffling, so examples and scripts are now fully separated.
• Install scripts into default location (not ~/dbUtils). (EDIT: Closes #5)
• Update setup.py to create a source distribution and update it for setuptools. It will use either distutils or setuptools for now.
• Document the release build process.
• Fix a few minor bits in the getting started documentation relating to dependencies and installation.

Note this also includes the commit to bump to 0.1.1rc0...the actual release was made from the previous commit, and that one will be tagged.

This is on testpypi, so it can be tested with:

pip install -i https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple/ dbprocessing

or downloaded from https://test.pypi.org/project/dbprocessing/

This should be merged at the same time as #124. Once the merge is complete, I will:

• Perform the upload to "real" pypi
• Tag the release on git and upload the files
