runtime logs automatically log to data/logs/runtime/YYYY-MM.txt

fixed giveruntimelog getruntimelog and getserverlog
Any admin with ADMIN rights can give anybody permission to view runtimes simply by typing .giveruntimelog The person given permission can then type .getruntimelog
Admins can type .getruntimelog without giving themselves permissions first
Moved a lot of the copypasta code into helper procs in __HELPERS/files.dm. There is one which allows a client to browse through folders on the server (in this case to look for logfiles). You can now also return to the directory you started at.

Note, for some weird reason, runtimes will no longer show in dreamdeamon. If this is a massive problem I can make it a compile option or something (or you can comment out the line if you're a coder). I know this is a massive pain but it sort of removes much of the effort in getting runtimes from other servers, since they all now have their runtimes saved in a way coders can easily access. It also sort of means we don't have to rely on people remembering to log runtimes and such. And all logs will be organised by month.
