  Bump structuremap version requirement

EPiServer.ServiceLocation.Structuremap requires structuremap version 4.5.2. This contains a potential memory leak bug

Partners can just update structuremap to get around this issue, but EPiServer.ServiceLocation.Structuremap should be updated because new/updated installations require a fixed version of structuremap.

If reasonable, the EPiServer.CMS package should be updated to require the new version of EPiServer.ServiceLocation.Structuremap.

EPiServer.ServiceLocation.StructureMap 2.0.3; (Or a related package);

  StructureMap: Duplicate assembly redirects in web.config
  1. Create a new site with Alloy MVC using VS (or remove assemblyredirects from web.config and install package to site)
  2. Open web.config

ACTUAL: Duplicate redirects of EPiServer.ServiceLocation.StructureMap
EXPECTED: No duplicate redirects

Note: Trying to update NuGet packages to newer version will now fail, update should handle duplicates correctly. Workaround is just to remove the duplicates.

EPiServer.ServiceLocation.StructureMap 2.0.1; (Or a related package);
