-added prev_frame_index to distrenjob queue
-mortition() now changes prev_frame_index to zero if the job is not completely done
-find_jobframe() now starts in the frameset array at prev_frame_index
-efficiency for finding every frame in the job goes from ((x^2)/2 where x = total_frames) to (3 * total_frames);

-created hibernate in general_info and distrenjob structures
-implimented it into find_jobframe() and the functions that initialize the jobs variables

-renamed blend_frame_watchdog() to frame_watchdog()
-frame_watchdog() now uses the variable watchdog_forgiveness in the distrenjob structure
-watchdog_forgiveness is now is seconds, since it is easier to specify a fraction of an hour with seconds using an integer, rather than trying to use a float or long.

-prepare_distrenjob() now uses distrenjob_new() to initilize the job, but then assigns values from the parameters to their proper distrenjob variables
-removed unneeded comments/TODOs

removed avg_render_time from distrenjob structure
removed time_remaining from distrenjob structure
removed percent_done from distrenjob structure
-- values that don't need to be calculated by the server

-added total_render_time to distrenjob structure
-changed finish_frame() to increase total_render_time by the time it took the frame to render
