##RD501 EMP adjustments
###Goal
While JLTS' EMP system works great, its weapon swap feature was deemed to taxing on the servers, especially considering the possibility of cluster-EMP that might hit hundreds of units.
To still have EMP effect guns, but avoid the switching, all guns not configured otherwise will jam when hit by EMP.
###Config
Default (no config params): Gun jams on EMP
To go back to JLTS behaviour:
If RD501_fryOnEMP is not set to 1, the gun will still jam, thus having the desired behaviour on default JLTS guns without having to edit their config.
