implement Num sqrt(int) and Num sqrt() for: (ta4j#266)

* added trailing stop loss rule * added trade-awareness, fixed Trade#equals if the TrailingStopLossRule is used in the context of other rules ( e.g. using OrRule/AndRule ), this rule might not notice that the current trade has changed; thus, the extremum is wrong. This commit fixes this issue. * added test-cases for Trade#equals * implement Num sqrt(int) and Num sqrt() for: BigDecimalNum, DoubleNum, NaN, PrecisionNum Num: add Num sqrt(int) and Num sqrt() NumTest: add sqrt(int) and sqrt() tests * changelog * numTest.properties: changed property names NumTest: moved into num/ and changed property names
