nassh: rewrite options page to be more Chrome like

Use the chrome-bootstrap project to get an options page that looks like
standard Chrome options pages.

We also change the theming behavior so that instead of modfiying the
current page, we actually create a small hterm window.  Now people can
see what the settings will look like, and we don't have to duplicate
the settings mappings ourselves.

BUG=None
TEST=looked at the options page

hterm 1.35: Add enable-bold-as-bright preference.

* Adds a preference to control whether or not the bold attribute from ESC
  "[ ... m" sequences also triggers bright colors.  Preference is on by default
  to match the behavior of xterm and previous versions of hterm.  Switch it
  off to enable bold font face in non-bright colors.  This is especially useful
  if you've overidden your 16 color palette to something other than the
  typical 8-dark/8-bright scheme.
