Pile of OSGi dependency generator fixes from Alphonse Van Assche (ticket #39)
- use Temp perl module to provide temp dir - re-enable deps solving in Require-Bundle, Import-Package, Export-Package OSGI properties - remove uses bundle of Export-Package OSGI property - use RPM '>=' as version operator to match OSGI '=' - remove all .0 at the end of the version string - typo fixes
