windowManager.xmonad: Make it configurable and extensible.

[the-kenny]

The previous windowManager.xmonad option only starts xmonad and
doesn't make ghc available. This assumes that the user has GHC with
access to the xmonad package in his PATH when using xmonad.

My (or specific: @aristidb and my) changes make it possible to use
Xmonad without adding GHC to any profile. This is useful if you want
to add a different GHC to your profile.

This commit introduces some options:

• xmonad.haskellPackages: Controls which Haskell package set & GHC set
  is used to (re)build Xmonad
• xmonad.extraPackages: Function returning a list of additional
  packages to make available to GHC when rebuilding Xmonad
• xmonad.enableContribExtras: Boolean option to build xmonadContrib
  and xmonadExtras.

[aristidb]

It should be noted that the commit also changes xmonad to accept a XMONAD_GHC option telling it which ghc to use.

Looks good to me.

Maybe add a "type = types.bool" for "enableContribAndExtras" option?

Whoops - sorry. Forgot that.

I'll push another small addition later today, please don't merge until then.

Force-pushed a rebased version to make merging easier. Should be ready to merge now.

Wait, another small addition suggested by @aristidb is incoming...

[ocharles]

Is that the patch that adds a full path to xmessage?

Yes, xmonad will now use XMONAD_XMESSAGE if set.

Looks very good, thanks!
