Picard "Standard" SamToFastq Updates

* Respect the max_records_in_ram property by passing along to picard command.  
* Set re_reverse default to true to match Picard default behaviour.
For other reviewers, it looks like this default was changed in Picard recently as online documentation said it defaulted to false but `java -jar /gsc/scripts/pkg/bio/picard/picard-tools-1.59/SamToFastq.jar` says it defaults to true.
