Merge pull request #3243 from xabbuh/fix-build-errors

Fix build errors
Replace gendered pronouns with gender-neutral

For consistency sake, instances of "he", "she", "his", "hers",
"his/hers", "he/she", etc were replaced with "they", "their", etc (or
were removed all together in cases where they weren't necessary). Verb
tenses should also have been corrected where changes were made.
