DockManager: add the ability to programmatically update splitter sizes (#266)

Browse Source 
Add the ability to programmatically update splitter sizes. The user must
specify the dock area that is contained in a splitter and a list of
sizes. The list of sizes will be passed to the splitter that immediately
contains the specified dock area. If the dock area is not part of a
splitter the method will have no effect.
