Clean file frames.lua to make more readable

- "#(array)" replaced with "#array"
- "(a and b) or c" replaced with "a and b or c"
- Cleaned some other places with unnecessary parenthesis
- "a,b" replaced with "a, b"
- "a+b" replaced with "a + b" (and for all other binops)
- "{a, b, c}" replaced with "{ a, b, c }"
- "-n + a" replaced with "a - n"
- Removed trailing whitespace
- Blank lines added in some very dense places
- Very long lines broken into shorter lines
- Use modern functions like vector.new and vector.round
- Align with spaces instead of tabs
