Added procs to quickly issue refresh of subsite theme parameters from current theme defaults. This is useful in a context with many subsites using the same theme, when desired behavior at upgrade is to have them reload all parameters automatically.
Unify version comparison logics so we always use apm_version_names_compare instead of other db api as apm_package_version__version_name_greater plus handcrafted queries which also might behave slightly differently
- do not depend on beta or development versions- make sure that released versions are not beta or development- align version numbers (e.g. use also 5.9.1 for xotcl-core)- bump version numbers to 5.9.1
