To continue providing renamed ender chests/player inventories we can no longer just provide an Inventory, a full InventoryView is required. To avoid confusion the old method has been removed entirely, leading to a major API revision bump.
Methods are now properly annotated @Nullable when they may return null. More descriptive exceptions are thrown when issues occur instead of just returning null.
This allows API users to prevent issues caused by multiple different copies of the Player being loaded, such as #49. Multiple instances of the same player could be obtained by calling IOpenInv#loadPlayer, waiting for OpenInv to remove it from the cache, then calling the method again.
The project was very messy and due to older Bukkit packaging conventions, 1_4_5 and 1_4_6 were sorted away from the rest of the versioned code. All of the versioned internals are now submodules of the internal module.
Rather than use the hackish existing method of abusing the shade plugin to combine "dependencies" for a dummy assembly project, we're actually using the assembly plugin.
Profiles are still split up between the parent pom and the internal module pom, but they're much more clean.
The API is now its own module and can be compiled and released as a separate file for developers. Soon, Bukkit ticket 20, you'll be closed.
