Add support for lxpanel 0.7+ (Bug 11108)

The LXPanel plugin API was completely changed in version 0.7.0
without any module versioning or backwards compatibility. This
patch make the plugin work with the new version while retaining
the ability to still build for the old version (based on checking
the package version at compile time).
