Add login history for user accounts

[ririko5834]

It would be nice if there would be option to enable login history, it should store the timestamp, IP address, browser, computer os of each login to database (it could be .sqlite or just .json file or just .txt file). Then there should be option on the dashboard to view login history after you login. There should be also option to set how many last logins should be stored per user account, default could be last 10 logins.

Hello @ririko5834, I have added login attempt history, check pull request #1260 and #1261

It would be nice to show alert box of last login attempt after you login to dashboard if enabled. Also there should be some setting to set how many last login attempts to keep saved (to avoid wasting disk space)

Could you improve it?
