Added additional handlers to TLinAlg for DotProduct and AddVec, to support "templetization" of SVM.
Little cosmetics in the thread classes.
Introduced now svm files (svm.h and svm.cpp) for large scale SVM. The goal is to over time replace all svm* files from before with modern implementation of SVM. Currently only supports linear classificaiton, hence temporary commenting of regression in the qminer TJsAnalytics.
