A system that manages the add-on at runtime.

To allow the management of the add-on loading/unloading at runtime.

Description:

Actually to use various scenarios that are possible when some add-on are available, and specially when different fictional ones are available, Celestia obliges the user to create several Celestia installations or to move some add-on file in or out of the extras folder or to change the extension of some file. After that it is necessary to stop and restart the program to see the changes.

Another tedious problem is caused by the fact that when an add-on is developed the file is modified and saved often. To see the effect of the changes Celestia must be restarted every time.

So is requested the capability to choose at runtime which are the add-on that Celestia has to load during the simulation. The choice is made by the user checking the items of the list prepared by the add-on registration feature (See FR16 for details).

Having this capability should be possible to use different fictional/scientific scenarios without restarting the program and without complex manual file management.

Some examples, of add-on file that should be possible to load/unload:

- Extended Stars databases;

- Asteroid belts files;

- Minor moons files;

- Extended ground locations;

- etc.

Since the in-place editing (see G6) won't be implemented the capability of loading/unloading some add-on file at runtime should be very appreciated by add-on developers.

When the add-on file is updated the capability of reloading an add-on disabling and re-enabling it should be very handy.

Another drawback should be the capability of splitting the very large datasets (like the extended stars databases) in smaller ones that should be loaded/unloaded separately.
