Refactor of build.xml to get rid of netbeans dependency.

This is just the first draft and is still lacking the test target to run the junit tests.

It has been tested (although quickly) to make sure that it does in fact load the plugin in oXygen.
added test functionality into build xml

runs NameDropper tests.

would like to move tests into a tests subpackage in the source
directory so all java is in the same place. should probably also mvoe
the json and xml files in tests/ into res so resources are in the same
place
build.xml cleanup to remove redundant things
fully working build script. need to add in the jar step for the oxygen xml updates to work
adding classpath and proejct fiel for eclipse as well as deleting nbproject.dist. i move build-impl to main level in case we need ot reference it more
moved tests into source directory to simplify build, keep all sources in src, as well as simplify classpath for testing
Refactor of tests to read test files from within jar. also added copy step to copy test files to build
added some missing libraries to .classpath so building from eclipse would work. also added eclipse and setup without an ide sections to the readme. please let me know if there is any documentation that i missted
