for instance accounting, every epplet has its own directory in
~/.enlightenment/epplet_config/<epplet-name>, transparent config file
handling is provided. Users only need to query for settings and change
settings. Config settings are saved automatically on exit, which
means that users MUST call Epplet_cleanup() before exiting. Every
epplet instance has its own config file. Also added a mechanism for
defining default settings.
Updated all epplets accordingly.
Look at ConfigTestEpplet.c for the details. It shows what instance it
is running as and keeps a record on how many times that instance
has been run in the config files.
