I'd like to finally make the threatened API changes in io.matlab.  These are:

1) No longer search python system path for mat files.
``loadmat('somefile.mat')`` will now fail if the file is not in your
current directory, and we won't search the python path for
``somefile.mat``:
https://github.com/scipy/scipy/blob/master/scipy/io/matlab/mio.py#L37.
 We threatened this would go away in the next version of scipy in
commit 08cfc9 May 29 2010, and put in a FutureWarning in e7be18e Nov
2008

2) Change default saved 1D shape from column vector to row vector:
https://github.com/scipy/scipy/blob/master/scipy/io/matlab/mio5.py#L817

Threatened with FutureWarning in f7d9b150 Feb 2009 . Mat4 already
saves 1D vectors as rows.

3) Raise an error when trying to save arrays with > 2 dimensions to mat4 format:
https://github.com/scipy/scipy/blob/master/scipy/io/matlab/mio4.py#L448

DeprecationWarning since 54ae37d2b Jan 2010

Is this acceptable to everyone?  If not, do y'all have suggestions
about how to proceed with these?

Cheers,

Matthew
