Ecosim may crash when saving TS data in older EwE6 databases

[jeroens]

Symptom:
Application crashes when saving changes to Time Series.

Reproduce:

• Open carie's 'Lab 3' test database
• Load time series
• Modify any time series data to flag the scenario as dirty
• Save the scenario

Cause:
Database of EwE6 pre-release candidates cannot be updated using Microsoft Access SQL. The tables EcosimTimeSeriesGroup? and -Fleet in this particular database have a compound primary key which was changed prior to the September release. The EwE6 save sim scenario code expects only a singular primary key and crashes.

Solution:
None at this moment. Access SQL does not support dropping existing Primary Keys, so we cannot write an update to fix this issue.

Severity:
Low since the database schema was changed prior to the September 2007 release. However, I logged this issue just in case it were to surface unexectedly.
