Sort Change Session list entries

Add an option to sort or just sort by default connection list entries which expand from button "Change Session", available in editor, schema browser, etc.

Reusing existing schema browser or editor windows is needed for working with many connections/databases due to each window using many resources (GDI handles).

With many open connections it's hard to find the needed one in the list - the entries are in order of connections made.

Agree, would like to drag the connection buttons to change their order vs stuck with order in which they were opened
