minor changes to the help text

Description and Impact
----------------------
Just changes the first line of help text (under NAME) accessed with `octopolo -h`:
* Sport Ngin is two words.
* `as` should be `at`.
* Two spaces between the sentences looks weird. (I know there's a religious war brewing here.)

Deploy Plan
-----------
Um, I think maybe a new version needs to be released and announced in order for everyone to pick up these changes in their brew gem. But I don't know enough about it.

Rollback Plan
-------------
* To roll back this change, revert the merge with: `git revert -m 1 MERGE_SHA` and perform another deploy.

QA Plan
-------
#### Happy Path Scenarios
* [ ] Type `octopolo -h`. Verify that the NAME section of the help text doesn't have any egregious errors.
