[html-formfu] caveat: yml config is hash not array

[Mario Minati]

Hi @all,

just to document this behaviour. (I'm not sure if this should be changed.)

The yml config for a form is interpreted as a hash, so no order is preserved 
and no double use of the same key.

I tried to do:
load_config_file
  - defaults
elements
  - ...
load_config_file
  - some_default_elements

That does *not* work as the second load_config_file overwrites the first one 
and the elements defined in 'some_default_elements' are displayed before the 
elements defined in the 'elements' section as load_config_file is interpreded 
before elements in the 'populate' function in ObjectUtil.

The work around is loading everything from an external file as underneath 
load_config_file the order is preserved, as it is an array:

load_config_file
  - defaults
  - the_specific_elements
  - some_default_elements

Greets,
Mario
