Made program more secure

- Made the format separation a random string of characters of a random length to stop any possible chance of gaining access to users' files.
- Changed comment wording to more accurately reflect what the code is doing.
- Added prints statements in the installer to let user know what's happening.
- NOTE: Installer does not check whether the format_string and format_separator are substrings of format_item_separator. This can cause extremely rare issues when there is a substring match. The issue is too rare to need extra code for.
