Update to Wine 1.5.10. This includes the following changes:
- New version of the Gecko engine based on Firefox 14.
- Support for OpenGL in the DIB engine using libOSMesa.
- Off-screen rendering is now the default in Direct3D.
- Some more WMI infrastructure.
- Various bug fixes.
Use --with-fontconfig during configuration, since we already
have fontconfig as a dependency.
