[OctDev] new release?

[Paul K. <pki...@ja...>]

All,

We need a new release to support octave-2.1.48 since
OCTAVE_LOCAL_BUFFER now requires #include <memory>.
I've updated the half-dozen files that require it
(inc. comm/gf.cc and sparse/make_sparse.h).

Here is my take on the changes since the last release.
Please correct any errors in octave-forge/RELEASE-NOTES 

* Support for octave 2.1.36-2.1.48.

  - lp() fix range error

  - fieldnames() now returns cell array
  - listen() bugfixes
  - ellipke() supports m < 0
  - extend deal() to handle [a,b] = deal(b,a)
