Subject: [PATCH] Add support for writing log file.

Writes robo3t log file into the same directory where settings are stored.
Log file has the same contents as log tab shown in the app and contains
history of all commands executed.

Enabled by default, can be disabled by changing: "writeLogFile": false in the settings.
