[Feature request] Add authentication to the logbook proxy service

[mic4126]

After dmm release the android client. I have tested the logbook can support mobile version API(maybe the same as web version) with proper setting.
The simplest way to use the logbook function is adding a virtual server in router forward the port to the computer running logbook.However, this will create a security issue.
A compromise solution is using vpn instead of opening a port but this will make the battery consumption of the phone worse and result in higher delay.

(Same local network)

Long tap on your current Wi-Fi on the Android device and select modify the configs and there is proxy settings inside the advance settings. ( -> Stack Overflow )
Fill in the local ip (e.g. 192.168.xxx.xxx) of your machine running logbook and the port your logbook is set. (e.g. 8888 in the following picture)

In the logbook go to Settings and uncheck "他のマシンからの要求を拒否する" (refuse requests from other machines) and "外向けポートは閉じておく" (close port for outside network)
