Update markdown to not have gendered pronouns.

Searched for and replaced all instances of "she's", "he's", "Miss", "Ms", "Mr", "she", "he", "hers" and "his" if they were found. Since this is the source of truth I don't find it necessary to update the .html and other representations.

Fixes: Issue #1 
This seems like it should be "its control" and "it can provision"
