Milestone Code Cleanup (2.4)

Smaller functions, that perform only one task. Makes code easier to read and prevents code duplication.

Get away from using classes to represent sections of the site, instead use them to represent objects.

Example: members class

• add/delete/update/merge member

address class

• add/delete/update address info for a member

relationship class

• add/delete/update relationship

Implement coding standards.

Make sure all files pass CodeSniffer.
