Run integration tests full screen

I added self.driver.maximize_window() to helpers's setUp,
making all integration tests run full screen (maximizing
the browser's window).

Made import key pair examples more specific.

Removed image specific ssh examples when using import key pair feature under access and security. Replaced with a single generic example.

Settings page ChangePassword page and their tests

Two new pages added: Settings page and ChangePassword page.
To test their functionality I wrote two tests:
1. test_user_settings_change
 * changes the system's language
 * changes the timezone
 * changes the number of items per page (page size)
2. test_password_change:
   changes the password, verifies it was indeed changed and
   resets to default password.

To allow the above I've made few changes in other places:
* projectpage - added the go_to_settings_page method.
* helpers - added Selenium's implicit wait for self.driver
  in order to use page_timeout for pages that don't load
  instantly.

Add a proper IPv4 sorter for jquery-tablesort

The default implementation provided with tablesorter uses a busted
regex and nonsensical formatter.  Add an explicit IPv4 parser/formatter
to Horizon and use it instead.

Add support for trove incremental backups

Added extra column to backups tables (under instances
and under backups) that will show Yes / No if the
backup is incremental (ie it has a parent)

When you drill down into backup details we now display
the name of the backup parent if this is an
incremental backup. This is displayed as a link with
the backup name so it is navigable

When you create a new backup you can now specify
an existing backup to use as the parent

Note: At some point we should probably have the
create backup dialog filter the available parents
based on the current selection for the instance.
However, so far I haven't worked out how to make
the backup parent choiceField change dynamically
based on user updates to the instance choiceField

Add knobs for setting MAC learning on ports

If the Neutron MAC learning API extension is supported, allow user to enable it
for a port. Also display the current MAC learning state in the Ports table and
Port Detail page.

Replace UserManager with None in tests

Don't access keystoneclient's UserManager in tests. This should be
considered private data of keystoneclient and is not actually used by
horizon tests.
