[Xymon] enhancement request: memory usage in real values

Hi,

In case someone is interested, I created a patch for this:

• renamed function get_mem_percent to get_percent

• created new function get_percent -> this searches for the 3 values for used, total and percent

• renamed function do_memory_rrd_update to do_memory_rrd_update_pct

• created new function do_memory_rrd_update -> the rrd created start with absolute-memory and contains the used and total values
