Logviewer keeps clearing screen and losing history

[dpackham]

Problem/Motivation

Log viewer Current version: 0.15.1 keeps clearing the screen, and I lose viewing previous logs

Expected behavior

for example, on HA boot, I would like to see the whole log since boot. this way, I can see any errors and correct them.

Actual behavior

On HA boot it keeps clearing the screen and I cant see previous log entries

Steps to reproduce

Just run it on HA boot and watch. it will clear the screen and you cannot scroll up anymore to view logs

Proposed changes

Just run and allow the whole log to be viewed. like a tail -f logfile.
