This patch fixes:
- processing huge amount of incoming data with different dates. 
- overwriting existing license poller archive that may cause data loss
- accepting truncated license poller data. Truncated license poller data will be moved to garbage
directory.
- overwriting licenseevents data (e.g. HaspEventsParser.license.haspevents) and handling of archives
under two or more data groups.
- preprocessing of raw logs on the server. Log data input is already preprocess in openit client.

This patch updates Open iT Archiver and configurations such as datagroup generation.
