Fix project dependency formatters

https://github.com/versioneye/veye/issues/12

- updated branch
- double checked dependency formatters for markdown, table, csv
- added the new license field (except for "pretty" - I didn't know what line I should put it in)

- version_current is the latest version of the dependency out (should be named version_latest)
- version_requested is the version used by the project (should be named version_used)
