FER: suppress the warning when doing Find in Files search

[rcmpayne]

Due to the issue that was fixed (see below) we are now getting prompted with a warning log line every time the file is split.

Please suppress the warring

WARNING: Line 153107 split at 64 KB in C:\Users\username\Desktop\Logs\20180516\File.txt

WARNING: Line 153174 split at 64 KB in C:\Users\username\Desktop\Logs\20180516\File.txt

Steps to reproduce:
1. do a find in files search on server logs that have loglines larger than 64KB


TextPad 8.1.0 (10-Nov-2016)
Issues Resolved:
Find in Files stopped searching files with lines longer than 64 KB. Now they are split at that length.
