Instead of having a symbolic link from ./site to the executable in
dist/build/blog-rekahsoft-ca/blog-rekahsoft-ca, a separate test
running script ./site-test and a Makefile (which is redundant), have a
single shell script that wraps the blog-rekahsoft-ca executable and adds
a test option along with a switch to start selenium (-s|--run-selenium).
Updated README accordingly and removed unnecessary Makefile, and
site-test. Moved the symbolic link ./site to ./%site.
