Pom changes as part of PR10

[chonton]

It was not my intent to include the pom change that changed the maven coordinates in PR10. You probably want to restore the following sections:

<groupId>com.jasonclawson</groupId>
<artifactId>jackson-dataformat-hocon</artifactId>

and

<url>https://github.com/jclawson/jackson-dataformat-hocon</url>

and

<scm>
  <connection>scm:git:https://github.com/jclawson/jackson-dataformat-hocon.git</connection>
  <developerConnection>scm:git:https://github.com/jclawson/jackson-dataformat-hocon.git</developerConnection>
  <url>https://github.com/jclawson/jackson-dataformat-hocon/</url>
</scm>

and
