Support entity reference field

Here's a patch to add entityreference support for Active Tags. It requires the 'create new terms' patch to entityreference from https://drupal.org/node/1472596#comment-7670605.

In entityreference autocompletes, the id appears in brackets after the matched tag, however this is not saved to the term name. The id can be hidden with https://drupal.org/node/1802916#comment-6945660 or https://drupal.org/project/chosen_ajax.

PS ignore comment in active_tags_taxonomy_autocomplete_validate.

Thanks for the great patch!! #1 worked for me.

Also, #14 at https://drupal.org/node/1472596 is the patch to use in combination with this.

RTBC and ready for release into the dev version?

confused - @bgilhome: why does it require the 'create new terms' patch to entity reference if we only wish to use it to reference existing terms (and not allow for creation of new terms).

is that other patch optional when applying this patch?

Sorry, I should have made it optional - I was using the 'add new terms' patch for a project at the time and patched on top of that. The above patch applies OK without the 'add new terms' patch, but I haven't tested the functionality, I imagine it should be OK.

FYI, for the add new terms patch, subsequent to #14 on https://drupal.org/node/1472596 there have been better patches submitted - around #28.

thanks - i was actually going to mention that entity connect module is the more 'drupal and entity' way to manage creating a new entity from an entity reference field (versus what looks like a deprecated patch above)

any thoughts from the module maintainers on this patch and whether or not it belongs in the next release of the module (or in future releases in general)?
