Further amendment to use new/delete to handle vector<string>

[christopherlam]

I guess the _main_matcher_info should be inited via new/delete instead of g_new0/g_free because of the vector.

I don't think this is a good idea without at least writing constructors and a destructor and getting rid of the coy typedef. It really should be the last step of a thorough rewrite into real C++ instead of "better C".

It's too difficult right now to safely convert to c++ so I'd prefer to use GList instead of vector<Transaction*>

I think it's much simpler to revert recent changes and move a few instructions in gnc_gen_trans_list_add_trans_internal which should does achieve the same result of fast imports.
