beep-1.4.12

Changes in beep-1.4.12 over beep-1.4.11:

• Document how to override and disable packaged udev rules.
• Changed the build system to be closer to the GNU makefile conventions, i.e.
  • only one compiler/toolchain per build
  • default installation is to prefix=/usr/local instead of prefix=/usr
  • use GNU style docdir= instead of RPM spec file style pkgdocdir=
  • etc.
  • Still not using a configure script, though, as that is complex. The user writing a local.mk with some definitions covers everyone wanting to use the same settings across make invocations, though.
