0.0.1-alpha.7 to 0.0.1-alpha.8

In this version we've added a new log formatting, and both of current log files (output.log and error.log) should be empty before next permanent-seeder restart. Here's an example:

permanent-seeder stop

# Upgrade `permanent-seeder`

cd ~/permanent-seeder/logs

mv output.log output.old.log # Optional: backup
mv error.log error.old.log # Optional: backup

echo '' > output.log # Empty file
echo '' > error.log # Empty file

permanent-seeder start
