Delete player profiles created by the original NewProfile system

[BinToss]

• [x] Check if the last-used player profile was created by the first NewProfile Generator. There's a small chance this won't work as intended if the first Short value happens to be the expected value e.g. keycode 0x0009 was written to that position.
• [x] If true, copy existing settings to a new blam.sav and overwrite the old one.
• [x] Do not delete anything else.
