various small fixes to the defaultfile model

1) For safety reasons we no longer remove the default directory after
creating it. This prevents an access error (on windows) and also a couple
of small exploits that could have been possible, resulting in undefined
behaviour.

2) Once "default_filename" is allocated keep it until the value has to change.
The value is finaly released once the program is ready to close.

3) When picking a new default file, grab the new string directly from the
GSList.

4) When storing the new default file from the preferences dialog, make sure
we also update "existing_filename" if needed.

Fixed some whitespace issues, made commit message and one of the comments
in the code somewhat clearer.
