mseed parsing errors are printed.

Proper warnings are raised when an error is encountered during the
reading of a MiniSEED file. In this case we raise a warning to be able
to at least read the parts of the file up to the error.

changelog
Better error message for full SEED files.
Removing extra space
PEP8
More defensive __str__() method for responses.

While strictly speaking not valid these responses do appear in the wild
and ObsPy should not crash when trying to print them.

Also removes an obsolete warning.

Also merged the StationXML doc from the master.
Fixing failing doctests related to 75f1cd05d8b792.
Added the ability to interpolate in the frequency domain to
Trace.resample(). Allows resampling with an arbitrary sampling_rate. Fixes
issue #857.
Use scipy.fftpack.rfft in place of np.fft.fft, raise exception if window
has th wrong shape, clean up
Merge pull request #859 from kaeufl/releases
