fix for use the library standalone in a plugin

[Mte90]

I use Taxonomy Core included in a plugin, without the priority the l10n support is not loaded.

Can you try a higher priority like 9?

I've do it some tests, the best solution is:

add_action( 'init', array( $this, 'l10n' ), 5 );
add_action( 'init', array( $this, 'register_taxonomy' ), 5);

Use plugins_loaded is not the correct way because the plugin that calls can be executed before the library. With this priority, the l10n files are loaded and the cpt are translated correctly.

I understand the 'init' hook usage. I'm just requesting that you don't do it so early, at a priority of 5. 9 is still earlier than standard, but still gives many levels of priority before it, in case it is needed for any reason. I guess I'm just not sure why you chose 5 as the priority?

i've choosen 5 respect to 9 because is used already in the code of Taxonomy_Core
