Remove the Mapping the Future project logo from header-rezone.php

[benlk]

Changes

This pull request removes the "Mapping the Future" logo from the header that is used on:

• page-neighborhoods.php - https://citylimits.org/zonein/
• page-communitywire.php - I'm unsure where this is used; my db copy says post 2988252 which is https://citylimits.org/communitywire-home/ but that's a 404 on prod
• page-neighborhood-info.php - https://citylimits.org/zonein/affordable-housing-101/ as an example

Why

For #147 because this logo is old

Questions that need to be answered before merging:

• [x] Is this PR targeting the correct branch in this repository?
• [ ] Do we want to try to merge header.php and header-rezone.php somehow, like for example having header-rezone.php load header.php? They're not that different, with the exception of:
  • the addition of a body class for rezone
  • the .rezone-header section containing the menu
  • js for the rezone menu
  • removal of the global nav, which we aren't using anyways
  • the addition in header.php of improved support for things like WordPress' title tag and wp_body_open
