Simplify footer.html template conditionals

[miketaylr]

In the following 3 spots in footer.html, it should be possible to make this a little more DRY by doing something like if request.url_rule.endpoint.includes('foo_')

webcompat.com/webcompat/templates/shared/footer.html

Line 19 in 93be91b

<li class="footer-item{% if request.url_rule.endpoint in

webcompat.com/webcompat/templates/shared/footer.html

Line 43 in 93be91b

{% if request.url_rule.endpoint in ['contributors_report_bug', 'contributors_reproduce_bug', 'contributors_diagnose_bug', 'contributors_site_outreach'] %}

webcompat.com/webcompat/templates/shared/footer.html

Line 61 in 93be91b

{% if request.url_rule.endpoint in ['contributors_build_tools', 'contributors_web_platform_research', 'contributors_organize_webcompat_events'] %}

We probably need to come up with meaningful groupings and rename the route method names so this trick would work:

webcompat.com/webcompat/views.py

Line 342 in 93be91b

@app.route('/contributors')
