Implements AJAX form posting.

This is somewhat of a hack for Essex, since the long-term solution
is a reworking of the way AJAX is handled. But it solves problems
in the interim and provides a significantly better experience.

Thanks to Andy Chong for pushing forward with the initial attempts
which lead to this patch.

Fixes bug 943518.

Fix AJAX form posting that work incorrectly if get() in base views
is overridden by subclass, e.g. EditRulesView and EditAttachmentsView
if they don't add X-Horizon-Location custom headers if redirect is
used. This mucking is probably the cleanest way to fix this in
the meantime.

Rework translation for panel and dashboard names. Marked more strings.

Uses ugettext_lazy to delay translation; reworks the __repr__
method to avoid using the translated form; and changes the
unicode method of the HorizonComponent class to actually return a
string coerced to unicode rather than a proxy object.

In the process, many more strings which had been missed have been
marked for translation.

Fixes bug 910297.
