Subject: [PATCH 1/1] 0.9.3claws25

* configure.ac
* src/common/sylpheed.[ch]
* src/common/version.h.in
        add version in numeric form to allow easy comparison

* src/plugins/demo/demo.c
        add version check
        - sylpheed version > plugin version => never allowed, sylpheed
          could contain unknown API changes
        - sylpheed version < minimum version required => don't load,
          API required not available (if linking does not fail)
