key_wait method does not work as expected

[spyoungtech]

key_wait seems to return immediately, rather than actually waiting for the key.

Additionally, the return values are different in AHK v1 versus AHK v2. In v1, a return value of 1 means there was a timeout, in v2, the opposite is true.

Lastly, a TimeoutError is never raised in any circumstance, contradicting the README documentation.

It's unclear how long this has been broken, but it has been broken for at least 6 months.

To smooth over the API differences between v1 and v2, the proposal is that key_wait be modified to:

• return a bool, rather than an int: False will mean there was a timeout and True will mean the key was pressed. This more closely resembles the v2 behavior
• not raise a TimeoutError

The API usage will now look like:

if key_wait(key, timeout=1):
    print(key, 'was pressed')
else:
    print(key, 'was not pressed')

Technically, this is a breaking change for AHK v1 users... but since key_wait has seemingly been broken for over 6 months, it probably doesn't matter that much.
