Fixed a bug in the IB datasource that would result in incorrect times
for daily bars under some circumstances.
OHLCBars can now optionally also contain the opening time of the bar in
addition to the closing time.
Client change: requesting instruments no longer starts a separate zmq context.
Added an "about" box.
Split up MyExtensions class into class-specific extensions classes.
HistoricalDataEventArgsToOHLCBar now correctly sets the date to the
opening time instead of the closing time.
Fixed a bug with IB instrument addition, instruments not added to the
database would still show in the main window.
Changed instrument cloning procedure, tags are no longer cloned for the
new instrument.
Reverted previous change, sessions are actually cloned. Tags still not.
Rewrote the instrument editing window procedures a bit, they make a lot
more sense now in terms of EF usage, and a couple of crashes were fixed.
Minor commenting change.
Added SessionStartTimesByDay() extension method to Instrument.
Minor commenting.
Removed unnecessary type declarations for inner struct.
Added a default host for sql server.
Typo fix.
Added a class to hold layout options for grid columns, to be used to save the user's layout choices.
Added extension methods to serialize/deserialize xml that describes the datagrid layout.
Grid layout options are now saved on exit and loaded on launch.
Changed the way the opening session finder works. No longer has problems with sessions starting on a previous day (e.g. GLOBEX).
