Tidy up of lots of little things. :)
Make the functions that use atoll have a #ifdef HAVE_ATOLL around them. I did this because freebsd doesn't have this function, and it doesn't need to run any of the functions in tools.h that uses them.
Removed getting of some data we didn't really need or use. Updated page_stats to work with linux. Fixed tools.h to compile nicely :)
Made network stats work with linux.
Useful tools, currently only one function. Function takes a file pointer and will read threw it until it hits a passed string. It will return that line.
