FolderPluginCatalog: unnecessary assembly loading #44

Hi, @mikoskinen.

Thank you for your great efforts on this, really appreciate it!

While testing this framework for my case, I found inconsistency with TypeFinderCriterias for FolderPluginCatalog. To be more precise, the problem is in FolderPluginCatalog.IsPluginAssembly method, as it uses the obsolete TypeFinderCriterias property to determine if the specified assembly contains plugins. https://github.com/weikio/PluginFramework/blob/master/src/Weikio.PluginFramework/Catalogs/FolderPluginCatalog.cs#L192 https://github.com/weikio/PluginFramework/blob/master/src/Weikio.PluginFramework/Catalogs/FolderPluginCatalog.cs#L248

As the result, if you configure FolderPluginCatalogOptions with the new TypeFinderOptions and not with the obsolete TypeFinderCriterias, it will treat all assemblies as those that contain plugins, which leads to unnecessary assembly loading.

I've already created a fix to this issue, but it seems that I don't have permission to push it. Could you please take a look?

Thanks, Vasyl

We have pushed a new 1.2.2 release to Nuget which should fix this issue. Let me know if you still encounter the problem.
