Ability to set the default value of the checkbox per content type

Here's the patch.

Is ready to do it for every bundle of every entity but only exposes the interface for nodes in the content type edit form. You can set the variable manually if you are interested in other entities.

$default = variable_get('pathauto_i18n_default_' . $type . '_' . $bundle, 1);

It gets a variable to store the default.

Sometimes the default was 1 and sometimes was 0 so I unified it to what I think is the sensible default, 1. Enable the module and you get the behavior.

I'm not able to run the tests for this module on simplytestme or my local machine. I'm posting a void patch to check if everything is green.

Still not able to run the test properly but looking at the test I think I know what happens: with the default set to 1 now it generates more aliases for nodes and the users aliases en up in the second page of the aliases list so I changed the test to be lees weak and filter by user.

Is not that.
Setting the default behavior for user entities to be 1 is the problem (inside pathauto_i18n_init_property). In this case the default language is trimmed from the prefix of the alias. in the tests ends up being "users/pathautoi18n" instead of "en/users/pathautoi18n" For the English language.

This only happens in the tests which is confusing.

Now I can run the test properly on my local machine altough you have to launche theme several times in simplytestme to get them green.

I found out that setting a prefix in an alias is a bad idea since if you are navigating the site in a different language other than the default you will get a prefix set by drupal. and if drupal finds that something is in the default language removes the prefix (the test fail).

I modified the test so it tests the same functionality but without the language prefixes (now they are suffixes).

Forget about the prefix gettting trimmed, it was getting the very initial pathauto default "users/[user:name]".
There was some static cache getting in the middle.

Great!
As I said

Sometimes the default was 1 and sometimes was 0 so I unified it to what I think is the sensible default, 1. Enable the module and you get the behavior.

I feel that the UX is not consistent because the option for creating aliases for all languages is checked by default when internally the value is 'unchecked' because you haven't made a choice yet.

For example line 70 http://cgit.drupalcode.org/pathauto_i18n/tree/pathauto_i18n.module#n70
and
http://cgit.drupalcode.org/pathauto_i18n/tree/modules/pathauto_i18n_node...

This causes that if you use the module without interface (creating nodes programmatically for example) you get a different behavior than clicking around.(i18n paths created or not).

For me the sensible default is TRUE but I don't really care.

Can you comment on what you think should be the default?
