Bump to v1.0.1, update README, optimize stripJC()

stripJsonComments() is now more compact, and hopefully efficient. In
particular, the newline and whitespace checks now prevent the rest of
the comparisons from executing if the current character is whitespace.

Also shortened variable names to enable collapsing more lines. While
normally this might hinder readability, I find it actually enhances it
in this case. At the same time, I also updated some comments and added
more explicit comments to explain why the conditions are organized as
they are.

Updated the README to make sure all the example index.html paths are
file:// URLs. Also updated the "Multilanguage project" section to show
mbland/tomcat-servlet-testing-example using the installed package.
