liblinear 1.6

actually almost nothing changed
liblinear 1.7

A new solver for the dual form of logistic regression is added.
See the paper http://www.csie.ntu.edu.tw/~cjlin/papers/maxent_dual.pdf
version 1.7.1-SNAPSHOT
upgrade to java 6
reimplement vector functions from BLAS

The liblinear java port until 1.7 uses the Java BLAS (Basic Linear
Algebra Subprogram) port from http://www.netlib.org/lapack that is based
on Fortran code.
However, this dependency is an overkill since only rather primitive
functions are needed.

Some unreachable code is dropped [1] and complexity is minimized [2].
Micro benchmarking shows that the new code is even faster while yielding
the same results.
Macro benchmarks show however, that this optimization has almost no
effect on training time.

[1] "incx" and "incy" is always 1
[2] folded the (unrolled) loops. modern compilers are smarter and thus
the execution is faster.
