Reorganized code to work as a BIMserver plugin. Changes include:
- Binaries now in "bin" folder instead of "target/classes"
- Made code less file based (using streams)
- Added service plugin with user-changable mvdXML file
- Moved antlr library to "lib" folder
- Added vecmath and jxpath libraries (BIMserver plugin system does not
play well with maven)
- Added BIMserver project references instead of absolute jar references
