Comment 3 for bug 1000046

Recently release v0.94 still uses "$ENV{HOME}/.shutter/" instead of testing to see if $XDG_CONFIG_HOME and $XDG_DATA_HOME directories exist, and then, if they do exist or can be successfully created, to use parameters SHUTTER_CONFIG_HOME = $ENV{XDG_CONFIG_HOME}/shutter" and SHUTTER_DATA_HOME = $ENV{XDG_DATA_HOME}/shutter" instead of all the needless repeated invocations of ENV for setting up each of the user files (accounts, session, settings etc).
