event_download: Fetch events from GitHub

[edwarddavidbaker]

Hi Andi,

This pull request swaps the previous download.01.org URL with GitHub. We merged readme.txt into README.md and those file paths are updated here as well. Please review when you get a minute. Additional steps/details are also tracked in the parent issue at https://github.com/intel/perfmon/issues/17 . Sorry again about any extra work or interruption this causes.
