while it still remains a good idea to port as many NULL compares and assignments over to nullPtr as feasable, we do still need to sort out how to better support scripted empty, false, and zero assigns for things like objectIDs.
this means we'll need to both fully convert the backend of the parser to support that kind of thing, but also alter most if not all exisiting NULLs. up to and including things like SAFE_DELETE. while that's certainly feasable, given there's aproximatel 400 nullptr assigns/checks prior to this commit, and roughly 1800 of the prior, if it terminates in a script call and not an aip one direct, we'll be dialing that back until such time as fork fully fopcused on converting and resolving any lingering mismatches is completed.
- New InputEventManager class. It will be used by 3rd party input
devices to generate Torque 3D input events.
- Expanded the input event signal to include three new floats and a new
integer.
- Expanded the number of joystick buttons to 48.
- The input virtual map is now extendable rather than hard coded.
- The input devices types are now extendable rather than hard coded.
- New SI_POS, SI_ROT, SI_INT, and SI_FLOAT input event types.
- New SI_VALUE input action type.
- ActionMap has been updated to work with these changes.
- Removed unnecessary references to platform/event.h
