Changed Start-Debloat Function Code, new function

I changed the Start-Debloat Function's code to use [regex] as explained in the following link: https://www.reddit.com/r/PowerShell/comments/7xzwah/4_whitelisted_apps_in_my_script_are_being_removed/\

Thanks to Reddit user /u/GavinEke for the help.

I added a new Function called FixWhitelistedApps which will run and check to see if the Whitelisted apps in the Start-Debloat function were removed, and if so it should bring them back.
