Reveal icon for password field

All password fields now have a "reveal" icon, that can be clicked
to show the password in the filed (if it was actually rendered by
the template) and hide it again.

Add ".copy" before extension when copying a Swift object.

When the object has no extension the string is appended to the end:
test.pdf => test.copy.pdf
test => test.copy

Fixing display order of data processing panels

The data processing panels were being displayed in a
non-optimal order.  This patch fixes that by restoring
the same order that existed in the old repository.

TEMPLATE_DIRS must be a tuple

With Django 1.7, TEMPLATE_DIRS must be a tuple. The
definition in horizon/test/settings.py must therefore
have a leading comma. Note that other definitions of
TEMPLATE_DIRS are already like this in Horizon, so
this just fixes the one instance which is wrong.

Fix broken Subnet Wizard by updating to latest library

Updated jquery.bootstrap.wizard.js to the 2014/7/11 version.
Updated from https://github.com/VinceG/twitter-bootstrap-wizard. 
The bug was caused by changing bootstrap version without updating wizard.
This version "Supports Bootstrap 2.2.x, 2.3.x, 3.0".

(More specifically, the old wizard code was listening for a 'shown'
event that was never getting fired; the event is renamed 'shown.bs.tab'.)

Disconcertingly, there is no version number on the file, and the
comment at the top of the file says "1.0" - which is what it said
before. The timestamp is all we have to version it with.
