Clear-Host only when differences

[ZHider]

I am using the watch-command module to track changes in catalog files. I've noticed that with the -ClearScreen parameter, the screen is cleared every time a comparison is made. And if the object being compared is not updated as fast as the wc-command comparison, the entire terminal is empty in the one loop where the object being compared has not changed.
So I would like to clear-host only when there is a change in the comparison, and then output the result.

I'm a beginner in powershell, so if you have any questions, feel free to ask, thanks!

Thanks for the contribution. I don't think a new parameter is necessary though, I can't see any reason why we shouldn't just move the existing $ClearScreen logic to where you've put $ClearScreenIfDifferent, which is a better placement.

@ZHider I saw you closed your PR. If you want to reopen it and modify it per the above I'll happily merge it.

Thank you for your reply! I'm more accustomed to using watch command on linux, so I haven't figured out what the original clear-host usage scenarios were. I didn't modify the original clear-host logic out of an abundance of caution. I'm relieved to hear you say that.
I've re-opened my PR, so please merge if you think it's appropriate. :)
