ENH speed up SVMlight loader using Cython's array support
...
Loading the binary covtype dataset from
http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/binary.html
now takes 1/3 less wall clock time, which includes disk I/O and
decompression (bzip2).
Got rid of ArrayBuilder in the process.

Replaced all BSD style licenses with "BSD 3 clause"
Not checked yet!
Removed duplicate "3 clause, 3 clause"
Removed trailing period if exists
Fixed some missed licences, still about 50 to do, but those can be automated
Think I got the last of them.
Apparently me and sed have different ideas of regex.
Found a few more

This feature is explained in http://svmlight.joachims.org/ and adds
the ability to control which pairs are considered when dealing with
pairwise loss functions (e.g. for SVMrank).
In order to preserve API compatibility, I return this information (if
present) as a second column to the y vector.
