Added Ability to Sort Forms and Solution Explorer in CartoPac Studio

Added the ability in CartoPac Studio to sort both the Solution Explorer and Forms Explorer alphabetically. There is a sort button on the top of each explorer panel that can enable/disable the functionality. The sort is only for display purposes and does not alter the stored values in the CSN.

Sort Button

When Solution Explorer is sorted, values are displayed in the following order: alphabetized features and tables, alphabetized domains, and lastly alphabetized subtypes. When the Forms Explorer is sorted, only the forms within libraries are alphabetized. The forms libraries remain in the order in which they were previously in.

This change only applies to the CartoPac Studio application.
