Update of the SEEDManual_V2.4.pdf to the latest version of August 2012
Bugfix for waveform plotting.

There a slight error in the data binning. It always occurred but only
manifested for certain data lenghts. Also added a test for it.
stream.plot(): More fixes

Found another sample count that messes with the binning. This should
solve the issue.
Using proper malloc() while writing MSEED data.

The datasamples pointer in writeMSEED() is now filled with a proper
malloc call and not the old and hackish resizing approach. Now also runs
on Python 2.7.4. Fixes #551.

Also changed the MSTraceGroup to a simple MSTrace as it is only used one
trace at a time.

Requires recompilation of the shared obspy.mseed library.
Fixing confusion of numpy.string_ dtypes.

test_writeAndReadDifferentEncodings() now works across different NumPy
versions. Fixes #552.

fixing a failing import
all public C methods need to be listed in .def file for win
arclink: check times in getInventory on channel level instead of
location level (i.e. on downmost level). this can help with faulty
location specifications around OK channel specifications. (see #586)
fixing incorrect entry point for obspy.db features
fixes #489

Small bugfix for blockette 60 initialization.
fixes #554
Replacing the numpy views with true type casts.

Views do not change the underlying data and thus do not work with
custom C code that expects raw data of the correct type.
