Fixed links to images in config and migration pages

https://fedorahosted.org/freeipa/ticket/1932

Description of problem:
Title is missing while configuring browser for the first time.

Actual results:
There is no title on this screen. I noticed it only on step 8 and later so I am not sure if title is also missing earlier at step 6 or not.

Expected results:
Title "Identity Management" is always present.

Fixed:
 * modified paths to images
 * fixed padding in ssbrowser.html
 * moved browser icons to ui folder
 * deleted unused images in html and migration folders (they are already in ui folder, and weren't deployed)
