A.F....... [ZBXNEXT-1133] Fix action.get to use selectFilter correctly. Ignore "formula" and "evaltype" values if passed to action.update outside "filter". Improve code style. Fix action condition validators to validate actionid and conditionid only on update. Fix parameters to formula calculation. Use same data structure in frontend as returned by action.get. Fix frontend to make new conditions to appear at the end of list always.
