x11-themes/neutral-xcursors: verbump to 20150106

Major overhaul since the previous version.

Neutral, Neutral Plus, Neutral++, and Neutral++ White themes are now installed
as opposed to only Neutral Plus before. All these themes share the same origin,
but have noticeable differences.

${PV} now refers to the most recently updated theme, see ebuild for more info.

Fixed bugs:
- migrate away from deprecated EAPI;
- install themes to XDG-compliant directory (see bug 582818);
- install XDG-compliant index.theme for Neutral Plus;
- drop examples USE flag, which simply installed cursors twice;
- fix mess in the dependencies.
