Bug 9420 [Revised] Work on Bootstrap for Koha: Circ toolbar

This patch converts the toolbar include file used by Circ and
Patron pages to Bootstrap, replacing YUI button and menu code
with Bootstrap markup.

To test, view any page in circ/ or members/ which uses
members-toolbar.inc (circulation.pl, moremember.pl, etc).
Buttons and menus should look correct and work correctly.

This version adds icons to the toolbar from the icon sprite included
with Bootstrap and revises the sprite to include two new ones, for
"copy" and "place hold" (for use in later patch). This customized
version is left in intranet-tmpl/img in order to keep
koha-tmpl/lib/bootstrap free of customized files.

Also added in this patch, a CSS tweak to override a style in the default
Bootstrap CSS for a class "close" which is already in use by Koha. To
replicate the Boostrap "close" class use "closebtn"

Comment: All buttons works, and they look good.
Tested with Chrome and Firefox. In Chrome I see the buttons with
drop-down a little (1px) below the others.
In Firefox the alignment is ok.
No errors.
