Allow PIN entry via keyboard when logging in

Suggestion: Add a non-default option, via the .ini or somewhere else, which allows the user to enter their PIN when logging in with their keyboard/typing.

Rationale: Back in the mid 00s, one of the most common forms of account hijacking in games like Maplestory and Runescape was the dreaded keylogger. This malicious program would record and report on your keystrokes, which was generally used to send your log in details to a malicious third party. The click only, randomised PIN was adopted to directly combat this specific type of virus, and it worked reasonably well.

Over the years, the types of viruses used became more sophisticated and RATs etc became the norm. Today the use of keyloggers is extremely rare, and the requirement to click those tiny numbers my old eyes cannot see is a minor nuisance.

My proposed solution is opt-in only - it does not reduce the security of anyone's account in a meaningful way, and makes life a tiny bit easier. It has been adopted in other old school games like Old School Runescape.
