adding harness method to clean up image paths for issue #90
fixing applet built to explicitly compile to java 5
Fixes classpath definition in build.xml
- The version of POI using is 3.7
Exclude Ant runtime when compiling using javac
- It is usually best to set this to false so the script's behavior
  is not sensitive to the environment in which it is run

Adds copyconfig task
* The copyconfig is intented to copy all 'instance specific' files to the
  current project. This avoid the needs of handling instance files with shell
  scripts
Updates task to deploy instance to use appcfg.sh
* Instead of using the defined macros, we use the /bin/sh to execute
  the appcfg.sh
Appends failonerror = false

* When copying the configuration files, set `failonerror` to false,
  to continue with the rest of files
Fixes Issue #116 - Changes the way of handling existing SurveyInstance

* If a `SurveyInstance` is preset, we check for a `QuestionAnswerStore`, if
  there is an entry for combination `SurveyInstance, Survey, Question` we skip
  processing that line, otherwise we store it.
Issue #116 - Fixes NPE when dealing with a previous SurveyInstance
