Bug#611529: Update to build with soundtouch 1.5

[Miguel Colon <debian.micove@gmail.com>]

Hello:

The proposed patched was made before libsoundtouch0-dev got renamed to
libsoundtouch-dev.

When the changes recommended in this patch get applied please also add
these changes:
1) Strip the soname from the name of the build dependency. Change the
two instances of libsoundtouch0-dev ( previously libsoundtouch1-dev)
in the control file to libsoundtouch-dev.
2) Tighten dependency on libsoundtouch-dev to libsoundtouch-dev (>=
1.5.0) . The reasoning is that soundtouch.pc is only found in
libsoundtouch-dev >= 1.5.0 .

Thanks in advance.
Miguel
