Improve regexp that matches functional tests

The regexp was added by @semanticart in a7024ef12b7c1fe362918267f4ed1d1.

This patch improves the regular expression in two ways:

1.  It adds escape characters (`/`) before the curly braces (`{`, `}`).
2.  It removes unnecessary question marks (`?`).

In regular expressions, curly braces are meta-characters used to specify
the amount of repetition, so they need to be escaped. The Ruby regular
expression engine is smart enough to figure out what to do in this case,
but it outputs the following warnings on that line:

    warning: regexp has invalid interval
    warning: regexp has `}' without escape

The question marks are not necessary because dot star (`.*`) matches
zero or more of any character.
Hopefully fix travis ci

In the logs it says that `rake` specified in gemspec file doesn't match the one installed in travis.
Make default filter case insensitive

We had an issue where for one developer SimpleCov just wouldn't work.   Turns out that in his terminal he had cded to c:\... instead of C:\... (Note the lowercase vs capital C).   Well Windows happiliy changes the prompt to lowercase.  This causes SimpleCov.root to start with a lowercase c:/.  And that causes the default filter regex to fail for every file.  Making the regex case insensitive solves this problem.  May also solve several other issues such as #77.
Added notice about #281
Add docs badge to README
exit with code only if it's Numeric > 0
SystemExit#status is Fixnum, so there's no need to check for Numeric
issue #305. prevent resultset loss by placing flock on separate lock file.
Fixed a few typos and grammatical errors in the readme.
Use bundle exec for travis.yml
Update docs badge in README

Update the URL of the docs badge to include it from inch-ci.org instead of inch-pages.github.io (the former being the successor of the Inch Pages project).
