Random Database Errors

[bannsec]

Getting random database errors when leaving the analysis module going. Some research is showing that this is due to how sqlite by default will journal using "delete" mode, which will rebuild the sqlite file after every update (which happens often).

Should be able to switch this to WAL mode to fix this problem.

Initial change looks good, but has the side effect of now requiring that the analysis tool also runs as root since it needs to access the wal file. Also, some file systems will not support this (NFS, maybe FAT), i don't see that being a huge issue though.
