added ls file to index
javascript part of ls... i wonder if it would be a good idea to Ls.formatTime to miscellaneous.js
php part of ls... nearly perfect... : )
definition of the size of a directory (we can define this as we like, because it's just a value)
some more functions for accessing the filesystem...
cool functions for user management...
i have no idea what i changed here
better version of request (now we can add key-value-pairs to data via .setData())
