[Forex Trader]

Problem:
1) after drawing many object in a chart, when change to high level period chart, it looks densely.
2) to set the object's visualization in the "object list popup menu" one by one is troublesomely .

Suggestion:

* in the object list, add a checkbox column -- "visible in current period"
when it checked, the select object will set to visible in current period chart.
