Modify script to change "EntryType" to an enumerated list.

[damiendehart]

Currently, the EntryType is imported into New Relic as a numeric value, but we would like to see this as an enumerated list. Perhaps we can break this into three attributes for EntryType, Code/Numeric Value and Message?

IE: Taken from here

1 | Error | An error event. This indicates a significant problem the user should know about; usually a loss of functionality or data.
16 | FailureAudit | A failure audit event. This indicates a security event that occurs when an audited access attempt fails; for example, a failed attempt to open a file.
4 | Information | An information event. This indicates a significant, successful operation.
8 | SuccessAudit | A success audit event. This indicates a security event that occurs when an audited access attempt is successful; for example, logging on successfully.
2 | Warning | A warning event. This indicates a problem that is not immediately significant, but that may signify conditions that could cause future problems.

Or something similar.
