Riya-Jobs Doc

Subject: Reviewing and Re-formatting the new Jobs Doc | WEB-493

#### Problem

Prettify the jobs doc and re-format any content which may have been messed up in translation of the old Jobs Doc to the new Jobs Doc

#### Solution

I made formatting and grammar changes. There was also some content and links missing or skewed in translation, so I fixed that as well as. 

#### Comments

I made sure to compare the content from the old docs to the new docs to ensure that they were the same

#### Possible improvements

Content within angled brackets in the old docs was not translated to the new doc, so I manually fixed. An improvement would be to try to fix the way the docs are parsed so that doesn't happen (Ticket: https://saucedev.atlassian.net/browse/WEB-521)
