Login to zabbix does not work if not default locale is set for zabbix login screen

[halsbox]

Hi
If Zabbix is setup with not the default locale for login screen (e.g. russian, as in my case), than POST request to login fails because of Zabbix expecting translated value for "enter" field (e.g. "Войти" instead of "Sign in"), while "Sign in" is hardcoded in zbxtg.py. Simple solution is to adjust data_api variable in login function of ZabbixAPI class to suite your locale. More generic solution is to request the Zabbix JSON API key and then use it to construct the cookie for regular request to chart3.php, here is the patch:
