changed the google-gson library version to 2.2.4 - research suggests that this will fix the travis ci build errors.
altered travis config
added explicit mvn install:plugin build step
fixed install:plugin directive for regexp-me
testing new pom - no more plugin and install plugin directive
removed commented build directive
removed repository declarations as a test
fully removed repository declarations. all our builds use the super-pom repository (http://repo1.maven.org/maven2/), and none of our dependencies (including javrosa and regexp.me, which can only be installed from a local repository) can be found in the repositories that were, now, previously declared.
