This PR adds an option to remember last opened Extensions, a new toggle button is added under Features > Extensions section of preference panel to enable/disable this feature.
When enabled, the user will see view extensions which were open while closing Dynamo in the last session.
When disabled, dynamo will not open extensions from the prior session or save their state.
The extensions are serialized in the settings XML file.

• When option is enabled, checks if extensions that were open while closing Dynamo during the last session do reopen.
• When option is enabled, checks if extensions that were closed while closing Dynamo during the last session do not reopen.
