Tags: 1:13.b.2.1-dfsg-1ubuntu1
* Merge with Debian testing; remaining Ubuntu changes:
  - Drop libwxgtk2.8-dev build dependency. Wx isn't in main, and not
    supposed to. (LP #438365)
  - Drop erlang-wx binary.
  - Drop erlang-wx dependency from -megaco, -common-test, and -reltool, they
    do not really need wx. Also drop it from -debugger; the GUI needs wx,
    but it apparently has CLI bits as well, and is also needed by -megaco,
    so let's keep the package for now.
