Officers / people revamp

[jameslzhu]

#16 and #21 are involved in creating an officers page: see hkn.eecs.berkeley.edu/about/officers.

I'd say this is feature-incomplete.

This will need a broader revamp, which will entail:

• Figuring out how to model officer history, which consists of 'officerships' that only take place over a single semester
• Displaying officer pages for each semester
• Giving assistant officers first-class support on the site (as opposed the current site, where assistant officers must be added through the rails console)
• Being able to add / remove committees / officerships from people (probably automatically implemented through the django admin interface, rather than through the regular site)
• Figuring out how to tie committees to the django permissions for groups
• Figuring out a good url scheme for all the people pages (officers, assistant officers
• Integrating this with the elections page (optional)
• Building the same thing for the committee member page (or just integrate into the main page?)

Admittedly, most of these can be ported from the old site at https://github.com/compserv/hkn-rails.
