Short jump display bug

There is a bug in display routine.
App shows `EB2` instead of `EB02`.

File: JumpCalculatorDlg.cpp
Line: 444

Current code:

Code:

```c

char buffer[50];

if (ShortJump)

        sprintf(buffer, "%s%X", opcode, computed & 0x0FF);

else

        sprintf(buffer, "%s%04X", opcode, Endian_DWord_Conversion(computed));



SetDlgItemText(IDC_EDIT2, buffer);

```

Mask for `sprintf` should be "%s%02X" instead of "%s%X".
