The base that comes with ghc-7.6.1 no longer includes Prelude.catch;
so these modules were changed so that there is no warning for
import Prelude hiding (catch)
At the same time these changes should be compatible with older GHCs,
since the catch being has never been the one in the Prelude.
* true error: more modules export foldl/foldl'/foldr, so explicitly use the Data.Foldable one
* -Werror error: transition from Control.OldException to Control.Exception, assuming everything was IOException
Rework of the Logger portions of patches originally from seanmce33@gmail.com
to apply without conflicts, plus several formatting utilities for use with
X (Maybe String) aka Loggers.
Improvements to DynamicLog include:
* Greatly expanded and improved documentation and examples
* remove seemingly useless makeSimpleDzenConfig function
* factor out xmobarPP
* add new ppExtras field to PP record, for specifying 'extra'
loggers which can supply information other than window title,
layout, and workspace status to a status bar (for example, time and date,
battery status, mail status, etc.)
The new XMonad.Util.Loggers module provides some example loggers that
can be used in the new ppExtras field of the PP record. Create your own,
add them to this module, go crazy! =)
