Add proxy, more session control

[makarworld]

Changes:

• add proxy support to all requests
• add cookies arg to init (if user saved session and want continue with them)
• add autologout arg to init (if user want to save cookies and use it again later)
• edit login method, if user provide username, password and steam guard when initialize class, method should not request
  them
• edit login method, if session is alive, skip login method

Example:

from steampy.client import SteamClient

client = SteamClient(
    api_key='XXXXX5FXXDDXXXXXABECXXB0C86XXXXX', 
    username='steam_login', 
    password='steam_password', 
    steam_guard='account.maFile',
    proxies={
        "http": "http://login:password@host:port",
        "https": "http://login:password@host:port",
    }, 
    autologout = False)

client.login()
print(client.is_session_alive())

Session Control:

Also i add option autologout in __init__ function for more session control.
When autologout is True, session will be ended with program end
When autologout is False, session will be not end and you may re-use cookies later

Now you can save session cookies and re-use it later.

import json
cookies = client._session.cookies.get_dict()
with open('steam_cookies.json', 'w', encoding='utf-8') as f:
    json.dump(f, cookies)

re-use example:

from steampy.client import SteamClient
import json

with open('steam_cookies.json', 'r', encoding='utf-8') as f:
    cookies = json.load(f)
    
client = SteamClient(
    api_key = ..., 
    username = ..., 
    password = ..., 
    steam_guard = ...,
    proxies = ...,
    cookies = cookies,
    autologout = False)
    
print(client.is_session_alive())

I dont like it readed here, it is loaded in login function and thus SteamClient can be used for some cases with API key and without guard. Guard can be hard to obtain so this is braking change.

Okay

I have a small problem with rebasing it with 1 commit onto current master, I will try to deal with it next week and make new version 0.92 of steampy when it is ready.

Ok merged it manually with master, closing this.

Autologout variable was delete, if you dont want to log out, just dont use with statement.
