This uses two new functions (not exported):
`workspacesA` traverses the workspaces in a StackSet.
`runOnWorkspaces` runs `workspacesA` with the X state.
The current definition of broadcastMessage seems to be O(n^2) in the number of workspaces because it uses sendMessageWithNoRefresh and sendMessageWithNoRefresh uses updateLayout and updateLayout uses runOnWorkspaces.
This changes broadCastMessage and sendMessageWithNoRefresh to each use a single
call to runOnWorkspaces.
`executeFile` encodes the arguments with the current locale's encoding,
and GHC as invoked during recompilation quite likely also outputs any
errors in the locale encoding, which we then read using `readFile` again
decoding in the locale encoding, so it really makes no sense to force a
specific encoding here. What was I thinking? :-)

When `stack build --silent` fails, the output is not helpful at all:
Errors detected while compiling xmonad config: /home/slot/.config/xmonad/xmonad.hs
ExitFailure 1
Please check the file for errors.
And even in other circumstances it's helpful to see the command that was
executed, as it makes it easy for the user to diagnose what's wrong.
That's where they belong. As XDG was more or less broken in previous
xmonad releases, we can assume few people use it so now's the best time
to move files around.
For users of `~/.xmonad`, this only causes intermediate outputs (.o,
.hi) to go elsewhere.

Some layout and layout modifiers that keep track of some window
properties don't do garbage collection and update their state when
windows are destroyed. By broadcasting this event, it should be easier
for layouts to clean up

utf8-string isn't needed since d9e3ebf531
(late 2014).
Most of the executable xmonad deps are unnecessary since
307b82a53d (early 2015).
Switch from data-default to data-default-class to avoid bringing in deps
and instances we don't need.
In some shells—like bash—the entire help message is shown in a single
line because a newline is printed as a literal "\n" character when using
echo. Some distributions[1] have /bin/sh linked to bash, and so new
users are likely to run into this at some point.
We could fix this by either removing show and explicitly adding an
escaped quotation symbol before and after the string, or by using printf
instead of echo. The printf solution seems more portable[2] and so I
propose we go with that one.

Users who are installing stack on systems like Debian stable or Ubuntu
may get really old version of stack—much older than we currently
support. Thankfully, stack can upgrade itself rather easily with one
single command, so mention that.
