making requests to something like example.com over a non-encrypted
connection now works. Binary files are unlikely to work at the moment
although I haven't tried. Also, non-encrypted doesn't work.
I have also changed a little about how tests work. Requests tests now
display much better.
I have started writing tests for the config functions. This has resulted
in a few changes to the config code (tests working I guess)
I have also added a special "all" config file which (as the name
suggests) runs all test suites
In the makefile I have added the compiled test files to the clean target
and added targets for building and running tests
