* Functions that used GetServer and then threw an error on null now use safeGetServer to do that for them.
* Parameter names for ip have been changed to hostname.
* Functionality of getPurchasedServers(false) to return an array of IPs was restored (it was broken by the change to hostnames as primary key).
* Dynamic ram message was updated to omit the part about modifying imported scripts, since this is no longer an issue.
* Dynamic ram violation samples were updated so that they would actually avoid using the variable name 'scan' (which would not subvert ram calculations).
* Included a fix for getServer to default to script's current server if no hostname is specified (per doc page).
