Fix regular expression of username format

Username format in VRChat log file is changed, so fixed regular expression.

Before:
[NetworkManager] OnPlayerJoined xxxxxxxx
After:
[Player] Initialized PlayerAPI "xxxxxxxx" is remote

Release v0.2

Fixed regular expression to avoid unwanted results like:
User: executing [AudioTrigger (False, 0.000, 0, "Audio Source", tirin1, 0)]
User: executing [AnimationBool (False, 0.000, 0, "null", Open, 0)]

Release vrc_world_user_checker.exe

Remove executable of vrc_world_user_checker.py
