This code works just fine with non-integer table keys. Also, this is used by
awful.screen.focus_bydirection() and thus will be used with screen objects
instead of screen indicies when we get rid of screen indicies.

Go around a limitation of the lua language spec. The return value
of this method guaranteed `ipairs()` correctness.
Please note that both the official Lua and Luajit implementation
provide a sparse table compatible `ipairs()` and __len implementation
by default.
This adds functions for getting directories according to the XDG base dir
specification. This might be useful in general.
This also adds a function for getting the cache dir, because I like an explicit
function call more than something which "switches" based on a string argument.
Better error messages if you mis-type something. :-)
Finally, this adds a function for getting the directory containing the rc.lua
file. Sadly, awful.util.getdir("config") did not actually do that. See #218.

* This commit add a new module to avoid a (4 level) loop dependency
* It is now possible to call awful.spawn() with a table of properties
* awful.rules is used to execute the rules.
* Everything is public to allow alternative workflow modules such as
Tyrannical to use their own callback implementation.
This new function spawns a program, similarly to awful.spawn, but captures its
output. On each line of output on stdout / stderr, a Lua function is called with
this line. There are different callbacks for stdout and stderr. When both stdout
and stderr are closed, another callback function is called. The intention for
this last callback is "the program is done", because most programs should only
close their output when they exit.

color_strip_alpha was used to insert colors into Pango markup, but it
did not correctly check for valid Pango colors. ensure_pango_color
checks if the color is valid in Pango, and returns a placeholder if it
is not.
