Fixed #28 - service install

This is a partial fix for install. Still fails for uninstall
Fixed #32 - New solr.xml format

NOTE: this also adds a patched solr.war including SOLR-4791 since else
sharedLib would not work. This must be removed when upgrading to 4.4 or
4.3.1
Fixed #34 - Logging with slf4j/log4j
Fixed #35 - better garbage collection opts
