Martin Hořeňovský 3b98a0166f Various small string usage performance improvements.
* Empty strings are now direct constructed as `std::string()`, not as empty string literals.
* `startsWith` and `endsWith` no longer construct new a string. This should be an improvement
for libstdc++ when using older standards, as it doesn't use SSO but COW and thus even short
strings are expensive to first create.
* Various places now use char literal instead of string literals containing single char.
** `startsWith` and `endsWith` now also have overload that takes single char.

Generally the performance improvements under VS2015 are small, as going from short string
to char is mostly meaningless because of SSO (Catch doesn't push string handling that hard)
and previous commit removed most string handling if tests pass, which is the expect case.

// deprecated and will probably be removed quite soon!

// In fact, ideally, please contact me anyway to let me know you've hit this - as I have
// no idea who is actually using custom reporters at all (possibly no-one!).
// The new interface is designed to minimise exposure to interface changes in the future.
