Rubyripper 0.4.2 release

[Bouke Woudstra]

Hi,

A new release has made it due to the terrible weather in the Netherlands
lately ;)

Changes are:

* kill a memory leak, reduces memory use a lot with long tracks
* removed the ruby-libglade2 dependency (ruby-gtk2 still needed)
* implemented a dialog for the case that an output directory already exists
* license included as a file: the GPL-3 License
* changed location of settings file to $HOME/.rubyripper/settings
* saving of (edited) freedb metadata to local disk
$HOME/.rubyripper/freedb.yaml
* added a .desktop file for auto inclusion in for instance the KDE menu
* a lot of small fixes

Kind regards,

Bouke
