Add description to ShowPivotAction for Studio about charts

[Flaurite]

Changes

Added StudioAction and supported two properties with StudioPropertiesItem annotation.

New API in com.haulmont.charts.gui.components.action.list.ShowPivotAction:

• void setExcludedProperties(String) // excluded properties separated by comma
  String getExcludedProperties()
  List<String> getExcludedPropertiesList() // returns parsed excluded properties list

• void setIncludedProperties(String) // included properties separated by comma
  String getIncludedProperties()
  List<String> getIncludedPropertiesList() // returns parsed included properties list

This API is designed especially for using form XML. Examples:

<action id="showPivot" type="pivot_showPivot">
    <properties>
        <property name="includedProperties" value="name, value"/>
    </properties>
</action>

<action id="showPivot" type="pivot_showPivot">
    <properties>
        <property name="excludedProperties" value="description"/>
    </properties>
</action>

For QA

1. Check new API from XML:

• for includedProperties
• for excludedProperties
