Log:
Patch from James Radley to allow override of the dotfile location.

Read environment variable GNC_DOT_DIR and, if available, use this
instead of `g_get_home_dir`/.gnucash.  This allows one develop without
impacting an existing stable installation, excepting shared GConf
keys.  Setting HOME does not help, because g_get_home_dir prefers
passwd entries.
