Allow parsing multiple instances

[masmc05]

This allows parsing multiple instances at once with better support of complex relations between instances (like if instance A uses suggestions from B and at the same time B uses suggestions from A)

Should probably update parseContainers to use the new method

[masmc05]

Updated the parseContainers, now if the priorities are the same, they will be parsed together in the new method.

        @CommandContainer
        class Test1 {
            @Command("test1 <arg>")
            public void command(Object sender, @Argument(value = "arg", suggestions = "test2") String arg) {
            }

            @Suggestions("test1")
            public List<String> suggestions(Object sender, CommandInput arg) {
                return Collections.emptyList();
            }
        }
        @CommandContainer
        class Test2 {
            @Command("test2 <arg>")
            public void command(Object sender, @Argument(value = "arg", suggestions = "test1") String arg) {
            }

            @Suggestions("test2")
            public List<String> suggestions(Object sender, CommandInput arg) {
                return Collections.emptyList();
            }
        }

By default now this works, but if one of the priorities will be higher or lower (for example @CommandContainer(priority = 2)), it will be parsed as in older version

I don't see the benefit to grouping the parsing by priority, I think sorting by priority for the collection passed to #parse should be enough

Ok, changed that
