[easytag/wip/application-window: 42/105] Remove main configuration file handling



commit 6da2aaf56848200897bfd4b4bbdf2c709506fa32
Author: David King <amigadave amigadave com>
Date:   Sat Jul 5 22:51:39 2014 +0100

    Remove main configuration file handling
    
    All user pereferences are now stored in GSettings. Mask lists and combo
    box histories are still stored in files.
