Purpose

The new RetainFolder functionality of the Package Manager is still not providing the desired functionality. This PR tries to fix some of the logic behind it.

Release Notes

• changes the way Publish and Publish Version load assembly files when retaining folder structure toggle is on
• stopped the ErrorString from being overridden when a specific condition is met leading to Resources.OneAssemblyWasLoadedSeveralTimesErrorMessage - this has not been tested fully, if it leads to some strange behavior later on
• also removed the limitation to loading multiple binaries with the same name, but located in different folders when creating a new package. This will allow, when retaining folder toggle is on, to create custom packages if necessary. If the toggle is off and the default folder structure is used, the duplicate binaries will be pruned in a different part of the code
