+MainForm should not be in Sq1.Gui/Singletons

+DockContentSingleton doesn't have to know about mainFormDockPanel and statusReporter; make deriveds to use global Assembler and make IStatusReporter obsolete(?)
+DataSourceEditorForm is restored on appRestart; if closed then is still restored but now shown (same zombification issue as with CsvImporter)
+DataSourceEditorForm left column tall boxes height autoadjust, leaving most other selectors visible (one more splitContainer)
+MAY_CRASH_Order.cs replace DataMember to JsonProperty everywhere and get rid of System.Runtime.Serialization
TODO after 56 backtests (optimization) Handles=45k !!! memory consumption is also my concern; can't profile that easily :(
+Qmock+autogen are displayed on the chart

+DataSourceEditorControl looks perfect
TODO draw two horizontal lines bid-ask
TODO renaming datasource creates a duplicate
TODO unmess StreamingSolidifier (null bars), ChartFormStreamingConsumer (null strategy), Bars.RaiseOnBarStaticAdded vs implicit push
