*CSR pinned on overview tab disappears on the first paint.
Cause
*Charts are automatically permanently disabled for charts that are initially empty
*This problem impacts any chart that is enabled in File => Preferences.
Details
*gGraph does not display layers (paint) when the layer is empty.
*gSummaryChart (layer) initializes empty to false and calculates empty during painting.
Causing empty charts to be permanently disabled.
*Once a chart has been displayed, it will always be displayed even if empty.
Solution
*Enabled painting charts when the DayRange is increased, triggering the empty flag to be recalculated
New non-empty charts will now be permanently displayed
*Overview maintains the largest DayRange used and list of empty charts.
*Overview receive these signals and calls recalculates when largest DayRange is increased.
*gSummaryChart implement recalculate method.
*gSummaryChart implement emit signal when empty flag changes.
*gGraphView implement emit signal when day range changes. (XBounds)
**** IMPORTANT MUST Rebuild makefiles.****
*Remove two Makefiles and execute qmake. (works for linux version).
a New feature has been been added but can not be activated until a UI file is changed - another submission.
This new feature will utilize the current displayed range as the custom range.
Other wise the Overview custom range uses the values from the calendar.
This changes does not require and data or translations.
