std/time needs a get_local_time function

[maximecb]

The std/time library could use a function to get the local time. One potential use for this, besides knowing the time, is as a random seed for the random number generator.

The std/time library is implemented in vm/packages.cpp. I think we should just use the ctime functions to implement this.

The get_local_time function should return an object with fields based on the C tm struct. However, I would rename the fields to make them more intuitive, eg: year, month, day, week_day, year_day, is_dst. I also propose that we do not include tm_year (years since 1900) because that is retarded.
