Configure.jar used to be used with firefox version < 10 which is not
supported anymore, thus this can be removed.

The intended course of action is to show manual configuration in
browserconfig.html instead of configuration with the extension
for versions of Firefox >= 40.

The reasoning is:
* plan for enterprise environments was not published yet which
  forces as to use AMO (addons.mozilla.org)
* with AMO the user experience is worse than a manual configuration

steps for AMO:
* go to AMO page
* installed the extension
* go back to IPA page
* probably refresh
* click configure
* confirm

manual config:
* go to about:config
* set  network.negotiate-auth.trusted-uris with *domain.name

  configured in different locations, add a note showing the different
  configuration locations.

Issue:
* There was no caching policy specified.
* -> Browsers use their own default policy.
* -> After upgrade, some Web UI files might have been actualized some not.
* -> With schema change may result into weird bugs in Web UI

Solution considerations:

1. Detect server version change and hard-reload at runtime
Detection is easy. Problem is the reload. Obvious candidate 'window.location.reload(true)' works in Firefox but not in Chrome because expected behavior when parameter is used is not in standard and therefore Chromium/WebKit authors did not implement it.

2. Application Cache
HTML 5 technology which lets web apps to run offline. Besides weird issues with event handlers which I encountered, this would be an ideal candidate. Simple change of manifest file would lead to reload of all files (requires reload of page to used the new files).

Showstopper was usage with untrusted certificate. If user did not add exception for the cert or its CA and would visit the page for a second time, all AJAX calls would fail.

3. Set Expires to now() for everything
Web UI rarely changes so this is an overkill. Setting it to different value is not a solution either. We can't predict when the upgrade will happen and when new Web UI will be needed.

Solution:
* Implemented a mini loader which loads basic resources. Dojo loader takes action after Dojo is loaded.
* The loader adds a version parameter (?v=__NUM_VERSION__) to all requests.
* Version is defined in the loader. It's set to current in `make version-update`.
* All static pages use this loader to fetch their resources.
* Version is also passed to dojo loader as cache-bust for the same effect.
* Expire header was set to 'access time plus 1 year' for /ui folder. Exceptions are HTML files and loader (set to immediate expiration).

Possible issues:
* Images are cached but not requested with version param.
  * Images with version and without are considered different
  * -> We would have to attach version to all URIs - in CSS and in JS. But we should avoid changing jQuery UI CSS.
  * Proposed solution is to change image name when changing image. Image change is done rarely.
* Version is set by build and therefore updated just on server update. It might cause trouble with different update schedule of plugins.
  * No action taken to address this issue yet.
  * We might leave it on plugin devs (own .conf in /etc/httpd/conf.d/)
  * or set expires to now for all plugins
* running `make version-update` is required in order to use static version of UI for testing

Manual configuration page for other browsers (ssbrowser.html) doesn't work in IE 10 - error page is displayed.

This patch is conditioning creation of Firefox configuration object so that configure.jar is requested only in Firefox. IE doesn't request it and so it does not fail.
