hterm 1.26, nassh Add user-css pref

* Fix ordering of some existing preferences.
* Add a 'user-css' preference, which will load a user-defined css file (by url)
  into the terminal document.  This could be used to load a web font, or to
  style the terminal in perverse ways.

Top level directories

  • libdot/ is a small set of JS libraries initially developed as part of hterm, now available as shared code. It provides a base layer for web applications. The code is intended to work in any modern browser, in either a plain web page or a “privileged” environment such as a Chrome platform application or Firefox extension. In practice, it's only been put to use in Chrome platform applications so far.

  • hterm/ is a JS library that provides a terminal emulator. It is reasonably fast, reasonably correct, and reasonably portable across browsers.

  • nassh/ is a Chrome App (currently a “v1.5” app, soon to become a “v2” or platform app) that combines hterm with a NaCl build of OpenSSH to provide a PuTTY-like app for Chrome users.

  • wash/ is a library for cross-origin virtual filsystems, similar to the Plan 9 filesystem. This directory also contains a simple bash-like shell environment for exploring these filesystems. The code in this directory is a work-in-progress.
