#242 Bad Save Location = No Startup

[Mark Goldey]

In windows, if either of the the mDefaultSaveLocation
or mDefaultTempLocation attributes is set to a drive
letter that doesn't exist, Furthur will not start at
all. For example, if the user saves the the h:/ drive
and that drive is removed or crashes, Furthur will not
start up. No error message is given.

A graceful solution would be better -- either a popup
asking for a new location, or simply starting the
application and allowing an error to be thrown when
Furthur tries to save something. Currently, w/o being
able to start up, the user can't even get into chat for
help.
