Plagman 548f939df5 Add horrible tracking template; for each structure you'll want to create a
separate tracker type by #defining __TRACKER_NAME and __TRACKER_GLOBAL_OFFSET.

eg.:

Then if you have a tracked value and a value of the same type at the given offset:

Tracker_1<int32_t> trackedInt;
int32_t trackedIntDirty = 0; // 4 bytes after

trackedIntDirty will become 1 everytime trackedInt changes.
