I've taken a look at the code and you have a little problem with
the new convar in it.
The plugin will always be disabled if you don't change the convar
at least once per map.
The way you coded it the bool variable that you only update on convar change
will always be "false" unless you use "sv_showhits 0" and "sv_showhits 1"
after that.
You might want to take a look at that again, after that's fixed it can
be approved
