Taxonomy Delete Language Neutral

Generally when we are using i18n module for translation then we always want to associate every content with some language. If you notice while adding/editing any node or term by default Language Neutral option appears in Language dropdown.

In order to hide default Language Neutral option from node add/edit form, i18n contains i18n_node module that provide an admin interface to manage this option. Similarly for taxonomy terms I was looking for some module but I did not get. Hence, just created this module to delete/unset Language Neutral option from Language dropdown for taxonomy only.

USAGE
1. Go to taxonomy page and edit any vocabulary.
2. If you choose "Translate Different Terms will be allowed for each language
and then can be translated", then "Delete language neutral from terms"
option automatically appears.
3. If you check this option then Language Neutral option will be unset while
add/edit any term from Language dropdown.
