Openrefine-client

- new command `info` prints metadata of a project
- new command `delete` to destroy projects
- projects may now be specified by name
- input format will now be derived from file extension
- refactored CLI
- tested with OpenRefine 2.7

* included urllib2_file.py in the package to ease installation
* generated one-file-executable for linux 64-bit with pyinstaller

extended the CLI with some options to create new OpenRefine projects from files

examples:
- ./refine.py --create example.csv create new project from file example.csv
- ./refine.py --create example.tsv --format=tsv --encoding=UTF-8
- ./refine.py --create example.xml --format=xml --recordPath=collection --recordPath=record
- ./refine.py --create example.json --format=json --recordPath=_ --recordPath=_
- ./refine.py --create example.xlsx --format=xlsx --sheets=0
- ./refine.py --create example.ods --format=ods --sheets=0
