FTBFS: 32-bit pointer assumptions in FTprocOrderDialog.cpp

[Emmet Hikory]

    freqtweak fails to build on 64-but architectures. In order to fix it, the following changes have to be made to src/FTprocOrderDialog.cpp:

213c213
< item.SetData ((unsigned long) (*mod));
---
> item.SetData ((unsigned) (*mod));
233c233
< item.SetData ((unsigned long) procmods[n]);
---
> item.SetData ((unsigned) procmods[n]);
444c444
< item.SetData ((unsigned long)proc);
---
> item.SetData ((unsigned)proc);
