rBuild 1.2.1 is a maintenance release.

• The product definition facade no longer uses the internal BaseDefinition class. (RBLD-289)
• The RbuilderClient class is kept around for backwards compatibility, and the _getRbuilderClient internal method has been made backward compatible with the earlier interface. (RBLD-290)
• searchPath entries without a troveName specification in the product definition are considered label search paths, and properly handled, both by the conary and the rmake facade. conaryfacade's internal _findPackageInGroups method was renamed to _findPackageInSearchPaths, to clearly indicate that packages are looked up on labels too. (RBLD-294)
• A dependency on urllib internals that is not consistent between Python versions has been resolved; previously, some successful calls to rBuilder resulted in errors. (RBLD-295)
