241784 - don't warn on target directory cleanup unless it actually contains 3rd party components

Status: RESOLVED WORKSFORME

(SeaMonkey :: Installer, enhancement)

Description

[Asa Dotzler [:asa]]

Right now (tested windows Mozilla 1.7rc1) we warn the user that we're going to
blow away the contents of the target directory even when there isn't any
offending 3rd-party component installed.  We should be more intelligent than
this. We should poll that directory and if the only files there are ours, then
not warn the user. 

Steps to reproduce: 
1. Do a clean install of Mozilla 1.7rc1. 
2. Do an install of Mozilla 1.7rc1 on top of the previous 1.7rc1 install.

Results: user is prompted that unrecognized 3rd party components will be deleted. 

Expected results: we don't need to warn if the only thing we're deleting are our
own bits. we should poll the directory and if the only files there are ours,
then don't warn.
