Added Changelog Management System.

A frequent problem on all SS13 codebases is keeping the changelog up to date, as the changelog is a horrible nightmare of bad HTML.  On top of this, pull requests that modify the changelog often cause merge conflicts.  For this reason, codebases without a strict update process don't bother updating the changelog.

To solve this, we at /vg/ propose this system, which decentralizes the changelog entries by developers into one changelog per developer (reducing the chance of a conflict), AND simplifies them into YAML, which is far simpler for git to handle.

Changelog *generation* is now performed centrally after a batch of PRs are pulled, and the system automatically generates HTML and timestamps everything.  A central "database" also keeps track of all changes to prevent duplication and allow further updates to be added to the same date, without creating a mess.  A templating system is also installed, to allow some customization of the output product without having to dig around in the python code.

 * Port requested by Cheridan.
 * Timestamp system has been updated to handle /tg/'s special snowflake timestamp format.
 * I've also had to fix some typos in the changelog itself in order to get the dates to parse, otherwise, b(e)yond some indenting changes and comment removal, it's identical to the old changelog.
 * Python 2.7 is required to run the genchangelog tool, as is PyYaml and BeautifulSoup 4.
 * And yes, I tested this, for once.
Fix empty author records being written.

Silicon Medical and Security HUDs!

- The AI can now access both Security and Medical HUDs via a new button
on its UI. The Medical HUD is exactly equal to all others. The AI's
Security HUD cannot detect implants.

- Cyborg HUD modules have been removed in favor of an inbuilt command,
to make it less of a hassle to access them.

- HUD code has been given its own file such that it can be used by any
mob. In addition, HUD users are placed into a list instead of searching
for only humans and checking them for a HUD item. This is to make it
easier to expand.

- Security HUD messages can now be received by any mob using a SecHUD.
RR's tweak + derpfix

Makes the sensor augmentation check for silicon instead of one for both
the AI and Borgs, since they are not actually different procs.

Reverts an accidental removal of the borg camera function, thinking it
came from NT's code.
Nerfs to AI's HUDs

- AI Medical HUDs require that the person's suit sensors be enabled (any
active mode) in order to view status data.

- AI Security HUDs display only the person's job as given by their ID,
no security status or implant detection.
