Added modificationDate field into Judgment class, added incremental dump support

see #87
It's generally OK, but you could just use @ModelAttribute JudgmentSearchFilter judgmentSearchFilter) - this way you wouldn't have to add all those parameters here and then build the JudgmentSearchFilter. I just think you do by hand what spring could do for yourself automatically. Even the extracting of local dates can be done by spring during mapping of request params to model attribute.
