Relative Time Fixes:

issue: mPDF Arabic Fonts

This addresses issue 4449 where using an Arabic language pack and trying to
print a ticket returns a PDF with either squares for text or no text at all.

This addresses an issue where searching for a Task by title returns all
Tasks in the search. This is due to the visibility filtering methods used to
filter tickets by staff's visibility.

This commit removes the logic that was used for time within 2 days which would give a result of either today or tomorrow when something could actually be in 2 days instead.

It also rounds relative time that is within 29 days so that the result will be more accurate.
Ex: 1.99 will round to 2 instead of showing 1
