About the PR: * We use "blocked" as an abstract term, when there may be different reasons * If there is a concrete reason, we use a more concrete word like "unstable" or "not useful" * Double negations like "don't block" or "block unstable" are avoided Besides this, this PR * Lets `Lv2Manager` hide the full `std::set` of plugin URIs * Fixes occurences of "BuffersizeLessThan32" - it is less or equal * Moves `enableBlockedPlugins` from Engine to `ConfigManager`
