util: BinarySerializer serializes and deserializes a file format version tag with every cubbie. This allows keeping old deserialization code around and working even as we improve things.

app.nlp.coref: fix broken import caused by the reverting of andrew's old commit
changed parse based mention finding to resolve duplicate mentions with the same boundary by taking the named one. Previously this was nondeterministic. We should always take the named one, since we often filter to just use the named Mentions downstream. This also gives deterministic features for coref.

Mention deduplication fix
fix failing tests
add "initializeWeights" and "finalizeWeights" to GradientOptimizer
optimize,classify: switching the classifiers to use leftMultiply instead of right multiply for better locality. Breaks serialized models for pos1 and parser1
TODO: Notes for next sprint.
optimize: making ParameterAveraging and AdaGrad behave well with the GradientStep changes; making initialization happen in a single thread for both
optimize: removing useless reimplementation of inheritance
