The test "Budget Investments Show milestones" was failing in certain
cases where `Globalize.locale` had been changed in a previous test.
Since having different values in `Globalize.locale` and `I18n.locale`
has proven to be an issue on the test enviroment, this commit also
changes application code in order to avoid similar situations on
production.
See issue #2718.
- Cleanup Translatable module (`translation_params` method too large)
- Move globalize_helpers partial to admin folder
- Use any class for method translation_params
- Helpers in `GlobalizeHelpers` make sure all are in use and see if they can be more legible
- Review js name clases and methods see if they can be more legible
- Refactor milestone views into partials with nice spacing between attributes
To delete a translation, a link has been added. This
link works for the selected language. It hides all the
things related to a language (the tab and the text_area)
and empties the text area, so that the value is blank
in the param hash. A variable called `delete_translations[]`
is changed.
e.g. If admin wants to remove English language,
delete_translations[:en] will be 1; if not, it will be 0.
When the milestone is updated, there is a before_action
callback that cleans the selected languages for deletion
(looking the delete_translations[] variable).
Because of the deleted translations are blank in param hash,
them won't be saved in DB.
