Title: Add last active and modified dates to tabs

These changes lay the foundation for future work built around tabs. By having an active and modified date, you can do a few things:

* Sort the `cmd-t` palette by date. In Sublime I used this to jump back and forth between two files I'm working on, but Atom sorts this list alphabetically so that dynamic is lost.
* Automatically close tabs after a certain time of inactivity. Sometimes I don't do the mundane work of cleaning up previously opened tabs. If I haven't touched a tab in a few hours, Atom could automatically close it.
* Style tabs based on their age. Think something like the heat map on [GitHub's blame view](https://github.com/atom/atom/blame/master/README.md).
