+keep "Parameter Bags" CTX open after ScriptContext switch (reverted to initial idea, ~3 commits ago, annihilated "crash on slider change while "Parameter Bags" CTX is open" changes)

+while switching ActiveDocument (ChartForm), tsiScriptContextsDynamic.Clear() and don't complain about missing ScriptContexts
+IndicatorsParametersInitializedInDerivedConstructorByNameForSliders: using IndicatorParametersByName (merged with Json) instead of IndicatorsInitializedInDerivedConstructor
+switching ScriptContext still overwrites its {ValueCurrent}s to the previous visible (new concept that IndicatorParameters are only identical objects between script context and sliders.tags, while every click-change is absorbed by snapshot.IndicatorsInstancesReflected)
+COMMENTED_TO_FIX_BEGIN crash on slider change while "Parameter Bags" CTX is open
+ScriptParametersById < ScriptParametersValuesById
TODO ScriptParametersById ShowBorder=false,Numeric=true after AppRestart (restored to default state instead of reading JSON)
