Fixes a host of runtimes caused by lag delaying "transmissions" between telecomms machines. Various objects were being deconstructed during this lagtime resulting in a bunch of weird null errors. Tested for 24hours on another server. Seems to be all ok.
Added some rudimentary checks to advanced proccall. Calling procs owned by objects is now a little less prone to runtimes. still a bunch of stuff to do to get it safe enough though.
