IDE-1329 Add deploy-excludes to package editor

Hi Greg,

I add the deploy-excludes part to the package editor. And I also sort the keys and format the keys to match the properties file. For the deploy-excludes format I referred https://issues.liferay.com/browse/LPS-11268:

deploy-excludes=\
**/WEB-INF/lib/xercesImpl-2.9.1.jar,\
**/WEB-INF/lib/xml-apis-1.3.04.jar,\
**/WEB-INF/lib/xmlParserAPIs-2.6.2.jar

Thanks.
