[Cleanup] Move somes elements to .ui files, improve translations.

LocationConditionDialog:
- Combined two separate state table into one;
- Only one of "block" or "fluid" group box can be selected, which will
enable the "state" table.

PredicateDock and MCRPredCondition now will be able to change language
automatically.
Items tooltips are moved to .ui files.
Some QTableView is converted to QTableWidget.
