Before this commit, there was a conflict between the spawn and
awful.rules rules.
Also, modules such as Tryannical monkey-patched this function to
add their own rules to the mix. This commit introduce a proper
API to add handlers.
The order is crutial for this to work, so a dependency system is
also added.
Fix#1482
Up to now, we always asked the X11 server for color allocation ("which
pixel value corresponds to (r,g,b)?", an AllocCollor request).
This commit adds direct support for TrueColor and DirectColor visuals.
In such a visual, the X11 server gives tells us where the red, green,
and blue color components are in a pixel value and we can then just
directly compute the pixel value.
Additionally, this commit adds code that assumes that in a depth=32
visual, the remaining values (after handling red, green, blue) is the
alpha channel for colors. Thus, this adds support for transparent client
borders.
This commit also touches code for the systray. However, the systray must
always use the X11 server's default visual and that one always(?) has
depth=24, i.e. does not support an alpha channel. Thus, the systray
background still cannot be transparent.
Also, in theory this commit should support visuals where some color
component does not have 8 bits, for example RGB565. However, this is
just theoretic and I have no idea how to actually test this (without
jumping through too many hoops).

* Add support for resizing notification icon with respect to aspect
Previously, if an icon was not exactly square, an icon size set in configuration
would cause the notification to pad the icon with empty space so dimensions are
equal.
Now behaviour is different: the bigger dimension of the icon is scaled to fit
the icon_size value, while smaller is scaled same amount to preserve aspect.
Also, ImageSurface is now not created as fixed size square, but it's dimensions
are computed in similar way.
* Round the computed dimensions of ImageSurface
Even one pixel off is still off.
This is a nice utility function that actually does what most callers
want, instead of signal_array_getbyid() which requires callers to come
up with the signal id.

This now does directly what previously awesome.load_image() did. Also,
this commit removes the only caller of awesome.load_image(), so that
function could (in theory) be removed now.

Adds unit tests for menubar.utils.lookup_icon_uncached.
Tests that icons and themes are found in the icon base directories, and
icons are resolved with the correct priority.
Creates directories and symlinks in spec/menubar/{home,usr} as test
data.
