Added new client-server incompatible checks:

Browse source 
* added strict mode (client and server versions must be same, see MAGE_VERSION_MINOR_PATCH_MUST_BE_SAME);
 * you must enable string mode after github code changes in serializeable classes (see #4459);
 * added client-side version checks;
 * added error message on wrong version disconnects.
