Comment is a reserved keyword for Oracle. The five 'Comment' columns are renamed to 'Commments'.
Migration scripts were modified to let oracle users create the database. For the others, migration 41 will rename the columns (only if columns have the 'old' name).
Fixed also a few oracle specific issues.

Note: currently (in Rails 1.2.3), there's bug in Rails oracle adapter. See: http://dev.rubyonrails.org/ticket/7344
Attached patch is required for redMine to work properly.

There's no aggregation reports for now, it's just possible to see all time entries for a project or an issue.
A new "activities" enumeration is added.
Permission for a role to log time must be set (new "Time tracking" section in role permissions screen).
