Add tests with lvalue inputs

Browse Source 
If the compiler supports forwarding references, we now test if lvalues can be used as input strings for split(), find_all(), and ifind_all().

Note that MSVC (without its recent /permissive- flag) may pass these tests without the forwarding references changes that I made, due to its non-standard binding of lvalues to rvalues.
