Fix several oddities in Project Converter

This is not a complete list. Nor are all of the changes exhaustive.
- Measure final execution time in seconds instead of milliseconds.
- Use `vformat()` instead of unreadable string concatenation whenever necessary.
- Replaces every `&` used with booleans with `&&` because Visual Studio was really complaining about it.
- Adds punctuation to some comments, in accordance to codebase guidelines.
- Fixes some typos around the file (such as "parenthesis" being called "parenthess"), as well as attempt to change some sentences to be more English-correct.
- Reworded some comments and error messages entirely.
