Implement inventory creation by type and title. Fixes BUKKIT-4045

With the current API it is possible to create an inventory with a specific
type, but it is not possible to give such an inventory a title other than
the default.

The commit changes that by adding a method to optionally supply the title
for the given inventory type and holder, creating the functionality to
display any supported inventory type with a 32 character length String.

If the inventory title supplied is larger than 32 characters then an
IllegalArgumentException is thrown stating so.
