tests: Added GTests for base/str.cc

Adding these tests supercedes the unittest/strnumtest.cc
and unittest/tokentest.cc tests. They have thereby been removed.

Function "to_number" in base/str.hh previously failed to cast negative
float/double numbers. This was due to the use of
std::numeric_limits<T>::min() instead of std::numeric_limits<T>::lowest()
to determine whether a string-to-float/double conversion was
"Out of range". Tests "StrTest.ToNumberFloatNegative" and
"StrTest.ToNumberDoubleNegative" exposed this bug. It has been fixed.

Methods "split_first" and "split_last" in base/str.hh have had their
documentation updated to remove abiguity in their functionality.
