Description of problem:
Please refactor alignment settings in Form properties section of form modeler to make them more understandable. Currently these settings are very chaotic and unnecessarily complex.

I see the following issues:

1) 'Label fields position' sellect affects field allignment for all 3 alignment options (Default, Aligned fields, Not aligned) even though it makes sense only for 'Aligned fields' option.

2) All 3 options (Default, Aligned fields and Not aligned) work exactly the same - when they are selected, the label is displayed in place which is specified by 'Label fields position'

3) The 'Automatic' option in Label fields position has the same function as would be expected from (Not aligned or Default radio button)

I suggest the following refactoring to simpify and improve understandability of these settins (see screenshot attached)

Version-Release number of selected component (if applicable):
BPMS 6.0.0 ER4

How reproducible:
Always

Steps to Reproduce:
1. Open some form in FormModeler and go to 'Form properties.

Additional info:
I understand this is a lot of steps, but I checked, that the underlying logic is localized in one class, so the changes should not be that hard to make.
