www/cpp-httplib: import cpp-httplib-0.15.3

A C++11 single-file header-only cross platform HTTP/HTTPS library.

It's extremely easy to setup. Just include the **httplib.h** file
in your code!

NOTE: This library uses 'blocking' socket I/O. If you are looking
for a library with 'non-blocking' socket I/O, this is not the one
that you want.
