Create Better Cookie Management Functions

[guyfleeman]

The current cookie management functions allow you to create a cookie, but has no functionality to store multiple items within a cookie. For example, within cookies.js you can find a cookie named C_BANNER_LOCAL_INFO. This represents a cookie name where we could set a corresponding value. The value should then be displayed under an info banner on the next reload/redirect. The problem is that we can't set more than one of these at the same time.

Ideally, we should be able to call some function to add multiple values under a cookie name. We should then be able to search and fetch some or all values for this cookie. This might mean storing values as KV pairs, but allowing blank keys when necessary. Any backing structure like JSON in the cookie should be abstracted away.

Functionality should include all items from the following list. The first three are currently present in cookie.js.

Direct/Simple cookie manipulation.

• set cookie (also update cookie with single value)
• get cookie
• delete cookie
  Multiple value cookie manipulation.
• add to cookie
• remove from cookie
• get from cookie
• get all from cookie

If the new cookie API sufficiently handles simple cookies in the multiple cookie interface, then we can consider making the first three items private.

This might be a very basic way to accomplish what we want. Just do it by cookie name and search regex matches. Could maybe wrap some basic regexes with functions for common use.
