This reverts commit cb35ce836903f6baa19cf577932e6d2b92f3fedb, reversing
changes made to f2f88b8c72d0c86d66232c2cb26a39ab40bca4f3.

Fixed #301

Attributes

Conflicts:
	openbr/plugins/gallery.cpp

Also, more careful memory management of the simplified transform in
AlgorithmCore

Conflicts:
	openbr/plugins/distance.cpp
	openbr/plugins/template.cpp

Rather than saving the Transform and distance strings of an algorithm
together, in stored files, save the transform and distance descriptions
separately. Also introduce an enum allowing for the serialization of
algorithms which use gallery comparison transforms, rather than distances
as their comparison function.

Update pre-trained algorithms, this only requires updating the algorithm
files themselves, transforms saved via LoadStore are unaffected.

…changed for loop to foreach loop
