Subject: [PATCH] Allow node to provide dynamic content to Info tab Closes #492

The node definition can now include an `info` property. This property can be either a string or a Function. Whenever the info tab is refreshed, such as the node is selected, the value of this property, or the result of the Function, will be appended to the Info tab.
