** window.GM_Exec(code, pswd): the same as GM_Exec

** - code: The code you want to execute in Tempermonkey Sandbox
** - pswd: The password you set above
** Remember:
** Calling GM_Exec with wrong password has no effect but to increase the number variable <triedCount>, your code will not be executed.
** For safety, you have to wait at least 1 second before you call GM_Exec again after you called it with a wrong password
** GM_Exec will be deleted if triedCount has reached a big number
** All these above is for safety, protecting your password from being tested out or guessed from the fucking crackers attacking you from their website
