Add option to warn if classes, methods, objects, and packages match a…

This way, a certain field can be rejected, e.g.

 <check class="org.scalastyle.scalariform.ClassNamesChecker" level="warning" enabled="true">
  <parameters>
   <parameter name="regex"><![CDATA[Util]]></parameter>
   <parameter name="match"><![CDATA[false]]></parameter>
  </parameters>
 </check>

will reject classes that have Util in them.

Added tests as well. If you choose to add this feature, I'll update the documentation and website as well.

Why does the coverage difference say 100% when the previous coverage was 87.09%?

[matthewfarwell]

Thanks for the PR. I'll have a look at it this week. For the coverage, I have no idea. It used to work.

[matthewfarwell]

Are you still interested in doing this?

[canoztokmak]

@matthewfarwell do you want me to take over this change ?

@SlideOn The diff percentage says "How many % of the changes made in this PR are covered?". Codecov uses many metrics to compare coverage, and that's one of them. It's like a "how thoroughly is this change tested?".

@matthewfarwell Sorry, I haven't looked at this in forever. From what I remember, I did all the code changes necessary, only the docs need to be updated. Is that what you're referring to? The merge conflicts as well, I guess.

@Adowrath Thanks, that makes sense.
