Add Consumer Complaint Database documentation

[cfarm]

Do not merge until 2/23

This PR adds the Consumer Complaint Database API documentation that currently lives at www.consumerfinance.gov/complaintdatabase/technical-documentation/ to the Open Tech site. This is part of the CCDB 4.1 project (see GHE for background: https://GHE/CCDB4/ccdb-4.1-planning/issues/12). This should not be merged until our project release date, 2/23/16.

• This has been QA across all supported browsers + bug fixes have already been made.
• Content + copy have been reviewed and this PR is being made to prepare for merge on 2/23 between 10am-12pm for the CCDB 4.1 project launch.

  Additions

• ccdb folder contains documentation pages for the Complaint Database API
• nav-ccdb.html contains CCDB specific navigation links
• new layout type, ccdb, to display CCDB-specific navigation include
• CSS from Capital Framework components:
  • cf-tables for the small screen stacked table styling on the Field Reference page
  • cf-expandables for the Release notes page - fixes the styling and functionality for all supported browsers (previous JS did not work in older IE)
  • cf-typography and cf-icons for the expandables show/hide + PDF icons

    Removals

• old expandables JS + CSS - this does not seem to affect the HMDA pages.

:tada: good job @cfarm!

Minor suggestion: rename notes.html to the more explicit release-notes.html.

[cfarm]

@Scotchester done. I also updated the cf.gov redirects file that pointed to notes.html

[Scotchester]

@cfarm Thanks! You rock :metal:

[cfarm]

Ready for merge 2/23

Some cleared content updates for release:

• Field reference for "Tags" + "Consumer consent provided?" fields. Also renamed the "Indexed?" column to "Notes"
• Release notes now say February for latest release

@ascott1 @Scotchester Just a reminder that we are scheduled to merge this puppy :dog2: between 11am-12pm tomorra. I will perform the delicate and complex procedure known as the 'self-merge' at that hour.
