Remove raise call from mouse.client.move

This makes move consistent with 'resize' which doesn't raise either.

prompt: CTRL+DELETE deletes history entries

Pressing CTRL+DELETE removes the visible history entry, if any, then moves to the next history entry (like pressing DOWN would do).
If the last history entry is removed the previous one is shown in the prompt (like pressing UP would do).
CTRL+DELETE works on history entries only: i.e. it has no effect on a command entered but not executed yet.
To implement above behaviour I added saving history table to file on Escape key press.

spawn: Don't try to spawn with empty argv (FS#1225)

When e.g. calling awesome.spawn({}), our argv array would be empty, so just a
pointer to a NULL pointer that marks the end of the array.

Since startup notification was enabled, this would then try to figure out the
name of the started binary. This would immediately dereference a NULL pointer
and crash.

awesome.spawn(): Check table arguments better

Previously, any not-string-convertible entry in the array argument would result
in lua_tostring() returning NULL which g_strdup() would pass through. Thus, we
would end up with a NULL entry in an array whose end is marked with a NULL
entry. This mainly means that we had a memory leak.

Fix this by actually verifying that we only have strings in the table that we
are looking at.

spawn: Remove useless argv[0] calculation

Since commit 3c40d6b, the passed in argument is decomposed into an array of
strings before the sn-related code runs. This means we already know argv[0] and
thus we don't need the code here that tries to figure it out again.

Do not raise clients in client_manage

Instead, use stack_client_push and emit the `request::activate` signal
from awful.rules.apply, if the client gets focus.

Fix Align Layout Fit Behavior

This changes the align layout fit function so that align:fit will not return
more space than is actually needed by its sub-widgets. Changes to align:draw
were also required so that any widget assigned to the middle slot will expand
to fill the remaining space.

Added Expand Modes

Added set_expand function with options of "none" "outside" or "inside" modes.
The "inside" mode is the default and will result in the original behavior. The
main benefit is being able to actually center a widget in the available space
with options of how to draw the outside widgets (expand to take the space,
or not.) Further functionality can be had by ommiting one of the outside
widgets. Set default layout mode in the constructor.

Add a "deep" option to awful.util.table.clone

This allows for having clones of a table, where its entries are still
references to the original values.

This is useful for copying a "default props" table, where you want to
keep the reference to entries like `awful.layout.suit.tile`.

Fallback to comparing layout names in awful.layout.inc

This helps in cases where you have accidentally cloned an entry from
`layouts`.

Previously, no current index would be found and the function would
silently fail.

scan(): Use less iterations for scanning for windows

There isn't much of a point in doing all the GetGeometry requests in an extra
run through the list. This commit merges it into the previous loop through all
windows.

This means that we now request some information during startup that we never
actually need, but I can live with that just fine.

Add end to end support for spawning tracking using startup notifications

This allow to spawn something, then apply some properties or rules when
the client show up ("manage").

This commit add:
 * "startup_id" property for all clients object (immutable, can be nil)
 * Second return value to awful.util.spawn() with the startup_id
 * Update the documentation

Example:

  local wait_for_it = {}

  local pid,snid = awful.util.spawn("urxvtc")
  wait_for_it[snid] = {ontop=true,sticky=false,
     tag = awful.tag.gettags(mouse.screen)[1] }

  client.connect_signal("manage", function (c, startup)
     if c.startup_id and wait_for_it[c.startup_id] then
        for k,v in pairs(wait_for_it[c.startup_id]) do
           c[k] = v
        end
        if wait_for_it[c.startup_id].tag then
           c:tags({wait_for_it[c.startup_id].tag})
        end
     end
  end)

drawin: Don't unconditionally redraw when made visible

Before this commit, we always threw away the drawin's cairo surface whenever it
was made visible and thus forced a redraw.

This commit changes this so that we only force a redraw if the drawin was
resized why it wasn't visible. To remember when this happens, we free the
drawin's cairo surface without allocating a new one when the drawin is resized
while not being visible. Thus, we then only have to allocate a new surface if
the drawin doesn't have one when it is being made visible.
