stub database migration for local logging
remove console and stat logging from database
checkDatabase function is not an api call, it should be internal
move console logging to local filesystem (stats are stubbed)
blank index and folder for region logs
stats logging to basic local files is working
log rotation mostly working, with the exception that file_put_contents updates filectime, so the initial rotate does not occur
changed perf file format to include date.  File rotation is now implicit, and files can be expired by checking the date in the filename only.
local logs now compressed as gz files using zlib
json decode sql field before passing as json for easier client consumption
updated web frontend to locate statistics in new position
update log view code to properly handle log not found errors
Merge branch 'localLogging'

Logs have been removed from the database.  Region console logs, region stat logs, and host stat logs, are now written to disk as compressed gz files.

Region console logs are wiped on each start, while performance statistics logs are wiped after the configured days.
