hterm 1.44: 'cursor-blink-cycle', bracketed paste, other fixes

* Fix Firefox detection in hterm.ScrollPort..decorate.
* Implement bracketed paste, BUG=chromium:393622
* Fix flash on paste, BUG=chromium:390357, BUG=chromium:394568
* Fix hollow-cursor-after-paste issue, BUG=chromium:390357
* Fix reverse-wrap.
* Add a 'cursor-blink-cycle' preference which can be a number or a two-number
  array.  If two numbers are provided, the first is how long a blinking cursor
  should be on, the second is how long it should be off.  If a single number is
  given it's used for both on and off.  Anything else results in a fast
  blinking cursor.  BUG=chromium:366206
* Hide terminal cursor when mouse cursor is over it, BUG=chromium:365910

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.
