* fix aliasing checks when the lhs is also transposed. At the same time,
...
significantly simplify the code of these checks while extending them
to catch much more expressions!
* move the enabling/disabling of vectorized sin/cos to the architecture traits

Warning 4512 (assignment operators could not be generated) is now simply disabled.
...
All unimplemented assignment operators have been removed.

remove sentence "Eigen itself is part of the KDE project."
...
it never made very precise sense. but now does it still make any?

* enable vectorization of sin, cos, etc. by default with an option to
...
disable them (-DEIGEN_FAST_MATH=0)
* add a specialization of MatrixBase::operator*(RealScalar) for fast
"matrix of complex" times scalar products (even more useful for
autodiff scalar types)

* patch from Konstantinos Margaritis: bugfix in Altivec version of ei_pdiv
...
and various cleaning in Altivec code. Altivec vectorization have been re-enabled
in CoreDeclaration
* added copy constructors in non empty functors because I observed weird behavior with
std::complex<>

* added a pseudo expression Array giving access to:
...
- matrix-scalar addition/subtraction operators, e.g.:
m.array() += 0.5;
- matrix/matrix comparison operators, e.g.:
if (m1.array() < m2.array()) {}
* fix compilation issues with Transform and gcc < 4.1

now have the Like1D flag.
* Big renaming:
packetCoeff ---> packet
VectorizableBit ---> PacketAccessBit
Like1DArrayBit ---> LinearAccessBit
