Many Thanks to Alondria for adding:

The list type and a bunch of support functions to LSL  
Added/ReImplmented: llGetListLength(), llList2Integer(), osList2Double() (note rename), 
    llList2Float(), llList2String(), llList2Key(), llList2Vector(), llList2Rot(), 
    llList2List(), llDeleteSubList(), llGetListEntryType(), llList2CSV(), llCSV2List(), 
    llListInsertList(), llDumpList2String(), 
Borked Still: llListSort(), llListRandomize(), llList2ListStrided(), llListFindList(),
Changed: llHTTPRequest() (Made wrapper of LSL_Types.list->List<string>)
