Removing projects field from component view and filtering the activities...

... and milestones by project when creating task from component view + bugfix

* When creating task from a project, project field should not show and the activities, milestones should be filtered list for that project.
* bugfix in change_password
No, you completely misunderstood this.

I said it is better to not add this field in the first place if it's not needed.

And if that can not be done for some reason (I don't see why it couldn't), then you should use a remover - which is a method of the object that you want to manipulate and not an external function! - to remove change the fields.
