Improve titles on 2017 API's root swagger pages

[MikeTheCanuck]

The 2017 APIs were deployed without much coordination or forward-thinking in mind, in terms of the overall naming scheme for each API's root swagger pages. The titles for each of the APIs are currently:

• Budget - http://service.civicpdx.org/budget/ "HackOregon Budget API"
• Emergency Response - http://service.civicpdx.org/emergency/ "Emergency Response API"
• Housing - http://service.civicpdx.org/housing/ "Housing API"
• Homelessness - http://service.civicpdx.org/homeless/ "Team Homelessness API"
• Transportation - http://service.civicpdx.org/transportation/ "Team Transportation API"

Whereas for 2018 APIs, we have things like:

• Transportation Systems - http://service.civicpdx.org/transportation-systems/ "Hack Oregon 2018 Transportation Systems APIs"

These titles are contained in the urls.py file for each Django application like so:

• Budget = https://github.com/hackoregon/team-budget/blob/master/budget_proj/budget_app/urls.py#L5
• Emergency Response = https://github.com/hackoregon/emergency-response-backend/blob/master/data/urls.py#L24
• Housing = https://github.com/hackoregon/housing-backend/blob/master/backend/housing_backend/urls.py#L6
• Homelessness = https://github.com/hackoregon/teamHomelessness/blob/master/homelessAPI/homelessApp/urls.py#L6
• Transportation = https://github.com/hackoregon/transportation-backend/blob/master/transDjango/APIs/urls.py#L6
