jsondoc maven plugin

Hi,

Just created jsonxoc-maven-plugin. It does the following:
* take all project dependencies (including transition)
* generate static .json file

Sample configuration:
```
			<plugin>
				<artifactId>jsondoc-maven-plugin</artifactId>
				<groupId>org.jsondoc</groupId>
				<version>1.0.3-SNAPSHOT</version>
				<configuration>
					<version>12.0</version>
					<basePath>http://localhost</basePath>
					<packages>com.st.apiserver.v2</packages>
					<outputFile>${basedir}/src/main/webapp/apidoc.json</outputFile>
				</configuration>
				<executions>
					<execution>
						<id>generate</id>
						<phase>generate-sources</phase>
						<goals>
							<goal>generate</goal>
						</goals>
					</execution>
				</executions>
			</plugin>
```
