function _flash_form_after_build in Flash Node 5

Various functions to manipulate the form after building in case default values are being reset. It also changes the description on the flash file field when a file has been uploaded, to help the user to identify which file is in use on this node. #parents is used as the identified in case the title is being translated. Not sure if this is the right way to achieve this, but it appears to work!
