Extra null character while generating strings

[navidcity]

pyVersioning generates an explicit null character at the end of each string literal. In C and C++ a null character is always implicitly present at the end of string literals.
For example currently pyVersioning generates something like this: .hash = "b541a64b8c840a97442c03050f1f92bb54128ba2\0",.
The null character at the end is not needed.
I don't know how string literals are made in Python though (whether the explicit null character is needed in Python).

Take char a[4] = "asdf\0" for example: https://godbolt.org/z/rvcnv1YE3.
With the \0 we get a warning that the array is too small. Without the \0, we don't get such a warning. So my recommendation is to keep the \0, in case somebody uses the array as a C-string.

So I'll change the strings to const char *, so we can remove \0.
