Improvements
- Users running without an sdcard in place would frequently run into issues where the camera stopped working. This was because log files are written to /var/log and gradually fill up the system. Since the file system is essentially memory based the camera would run out of memory and everything would stall. This version introduces a custom logrotate to be able to rotate files. It also modifies the logrotate code to ignore permissions since FAT32 systems (which the sdcard is mounted as) does not have permissions. Otherwise it would not work. Also the videocapture process can be sent SIGUSR1 to force it to reopen the log file.
