Some script parameters marked as required incorrectly

[AndrewBWS]

When configuring the longoverdue cron, several values are marked as required when they should not be. The cron will fail if no value is provided for --l, but does not truly require values for:

• --c
• --maxdays
• --category
• --skip-categories
• --list-categories
• --library
• --skip-library
• --itemtype
• --skip-itemtype
• --skip-lost-value

The runreport cron similarly has several values marked as required when they should not be.
I've not evaluated all of the other crons for this, but it seems that work is required.
