Implemented hook_enable to change module weight in order to support modules like e.g. select_or_other

Code cleanup. Removed cck functions from the D6 version, introduced some helper functions, added checkbox support

No more inline javascript, all is handled by Drupal.behaviors, main benefit is that it supports ahah operations

  text: textfield + textarea
  numbers: decimal + float + int
  file: file + image

Added code for cck decimal field as proof of concept
