Simplify path logic

Code Style

Return a compile-time object

Instead of creating a temporary QStringList
appending some items to it and returning, I'm
creating a compile-time QStringList with compile
time QStrings.

Const Correctness on ACBF

too many files touched but this is just const-correctness

Reduce Temporaries

d-pointer with unique_ptr

const char * to QStringLiteral

Use compile-time lists instead of runtime generating it.

Also, simplify code - create a few helper functions to
return the result of the calculation instead of creating
them inside of the switch.

Create a Common static library to remove duplications
