If a widget has a width/height of 0, we can safely draw it without running out
of the available space. This code checks if we got enough space after we now how
much space the next widget wants.
This fixes the systray. It has to be drawn at least once so that the C core can
set up stuff correctly. However, thanks to the systray having a width of 0, it
wasn't drawn by the layout.

The icon should get the same background everything else gets. Fix this by making
the background the outer-most widget in each item.

We need a fixed layout here to make tag names like "media" work. Without this,
every take would get the same space, no matter how long its name is.

They can and should now be done via gears.color instead. It was porting ever
since this was ported to oocairo anyway...

This implements objects in lua. Objects provide the signal functions that are
known from the C API ({dis,}connect_signal(), emit_signal(), add_signal()).

It seems like with lots of bad luck, the garbage collector manages to "steal"
the table with the buttons right after we decided to use it. Evil collector!

The data table is used to map objects (clients/tags) to the buttons associated
with them. This is done so that we don't have to re-create the button objects
each time this lists are updated.
The problem was that this weak-keyed table was never cleared, because the value
had a strong reference to the key (via the button's signal):
btn:connect_signal("press", function () b:emit_signal("press", o) end)
"o" is the key in the table and btn is reachable from the value. This prevented
the garbage collection of the key. Using a weak-keyed and weak-valued table
fixes this.

This adds a lua module for parsing colors. Named colors like "black" aren't
supported, but #rrggbb and #rrggbbaa colors do work.

EWMH describes desktop windows like this:
"_NET_WM_WINDOW_TYPE_DESKTOP indicates a desktop feature. This can include a
single window containing desktop icons with the same dimensions as the screen,
allowing the desktop environment to have full control of the desktop, without
the need for proxying root window clicks."
An example for such a window is nautilus' virtual root window. Naturally, such a
window would always overlap with any given client, so awful.placement.no_overlap
just didn't do anything at all. The fix is to ignore such clients for placement
calculations.
