Command-line tool to help manage the artifacts.

Current supports:
 - searching which project.xml's and block.xml's depend on a certain artifact
 - renaming artifacts across project.xml and block.xml files
 - updating an artifact version across project.xml and block.xml files
 - updating the version number of all artifacts belonging to a group across project.xml and block.xml files

Usage examples:

after compiling by executing 'maven', go to the root directory of daisy
(or any other project)

Executing:

sh path-to-daisy/tools/artifacter/target/run.sh -f daisy:daisy-repository-api

will list all project.xml and block.xml files that depend on the artifactId
daisy-repository-api within the groupId daisy


Executing:

sh path-to-daisy/tools/artifacter/target/run.sh -r -o daisy:daisy-repository-api -n daisy:daisy-repository-api2

will rename the daisy-repository-api artifact to daisy-repository-api2 by adjusting all
dependencies in project.xml and block.xml files, and will also adjust the groupId and id
elements in the project.xml file that creates the artifact (if found).


Executing:

sh path-to-daisy/tools/artifacter/target/run.sh -u jetty:org.mortbay.jetty:4.2.20

will update all uses of jetty to version 4.2.20


Executing:

sh path-to-daisy/tools/artifacter/target/run.sh -g daisy:1.6

will update all daisy artifact version numbers to 1.6
