Only minor rearrangements necessary to make that possible with C++20
And while at this change (which requires a full rebuild of Lumiera)
- simplify the defined comparison operators, as C++20 can infer most variations
- also mark various usages of `const char*` either as Literal or CStr
Remark: regarding copyright, up to now this is entirely my work,
with two major creation steps in 2008 (conception) and
in 2017 (introduction of a symbol table)
