Required Files : Potential error with incorrect Layout modifiedDt

[PeterMis]

The createFromFormat() function on layout->modifiedDt added in 4.0.7 release to the Required Files function in Soap, can cause the RF to throw an error Not enough data available to satisfy format if the modifiedDt isn't what we expect.

This is most likely to occur with older media/playlist Layouts, as they were incorrectly created without modifiedDt ( Fixed in 4.0.5).

To cover this and any other potential issues with modifiedDt, this function will likely want to be surrounded by a try/catch.
