Add key command to toggle log on/off

Browse source 
Add key command 'ctrl-t f' which will toggle log on/off.

If no log filename has been specified via the 'log-filename' option then
tio will automatically generate a new log filename every time the log
feature is toggled on. Meaning, when toggled multiple times, multiple
log files will be generated.

However, if a log filename has been specified, tio will only write and
append to that same file.
