Color Palette: get back horizontal padding - SL #4325

The PaletteWindow lost the horizontal padding when it started to be
used as replacement of palette menus.  So now each implementation has
to add the padding.

Improve XOColor fallback logic

We was failing if the value in gconf was None. Also parsing
the string once just to see if it's valid was pretty dumb.

Add API to close an html activity

We are exposing it using a websocket server. The port of the server
is passed in the search string of the file:// url.
Require authentication before making API calls

Otherwise anything might access the bus.

Note: This will not work if the user moves to another html page.  They
will not have a port/key passed in the query string of the URL, so
they won't be able to connect.

Don't set ACLOCAL

The m4 directory is specified in configure.ac. This export breaks
ACLOCAL_FLAGS and makes it impossible to build with
gobject-introspection in a non system path.
Ensure we cleanup the tmp dir

Even if the tests fails.
Palettes: remove comment about deprecated API

We make use of this API in the shell and in the toolkit itself
and never removed those deprecated calls. Let's leave it like
this for now and remove the comment.
