Xpad 2.10

Xpad 2.10 is now available. I fixed a possible crash when deleting pads while autohide toolbars are enabled, made toolbar icons smaller, and made the toolbar appear inside a pad when there is enough space instead of resizing the pad. I also added Slovak and Slovenian translations from Andrej Kacian and Matej Urbančič, respectively. The Gentoo maintainer Fernando Pereda provided patches and suggestions for this release, so thank you.
