Add some little string functions to Utils.cpp.

These functions check whether the beginning and end of a std::string match
a supplied prefix or suffix, and remove that prefix or suffix, returning the
remaining part. They are almost but not entirely trivial, and giving them
names makes the code that uses them much more readable.
