RPM builds

I've made a few changes to the hobbit.spec file which make it easier for me to customize the building of hobbit RPMs. I've attached the new spec file and the modified init and logrotate files, in case anyone is interested.

To customize the RPM, change the definitions at the top of the spec file. Place the init and logrotate files in your RPM_SOURCE_DIR (along with the hobbit tarball). Then run 'rpmbuild -ba hobbit.spec'

I thought this might be useful to others who want to change some of the defaults.
