fixed bug in filesystem.mounts; autorun scripts can now also be called `.autorun` or `.autorun.lua`, to allow 'hidden' autorun scripts; filesystems do no longer count towards the component limit. this is to make utility filesystems feasible; internet card now also attaches a file system that contains internet library and specific programs (pastebin for now); robot also attaches an additional file system that contains robot specific library and programs (dig for now)
renamed an nbt tag used for server->client sync which may help resolve #111 (though it shouldn't, really); catching any errors generated when parsing tile entity description packets and logging them, which should avoid weird things like #111 crashing the game
